Penetration of electromagnetic velocity fields through a conducting wall of finite thickness

The penetration of electric and magnetic velocity fields through a conducting wall (with \ensuremath{\epsilon}=1, \ensuremath{\mu}=1) when a nonrelativistic charged particle is traveling outside parallel to the wall is calculated for a good conductor in a perturbation analysis through first order in the velocity ratio \ensuremath{\beta}=v/c. It is found that the magnetic field behind the conducting wall is of a universal character depending only on the displacement of the field point from the charged particle outside the wall; the field is modified by the presence of the conducting wall but is independent of the conductivity, the thickness, or the relative placement of the wall. Within the conductor, the magnetic field depends upon the thickness of the wall but not upon the conductivity of the wall. In front of the conducting wall, the magnetic field is independent of the conductivity or the thickness of the wall. The electric field inside and outside the conducting wall depends upon the conductivity and thickness of the wall. In the region behind the wall, the electric field falls off as ${\mathit{r}}^{\mathrm{\ensuremath{-}}3}$. The currents in the conducting wall are independent of conductivity but depend upon the thickness of the wall. The electric field in front of the wall exerts a dragging force on the passing charged particle, providing the energy balance for resistive heating in the wall. This dragging force increases as the thickness of the wall decreases. The present general analysis extends earlier work in the literature that treats the special cases of an infinitely thick conducting wall and of a thin perfectly conducting wall. The ideas involved are unfamiliar to many physicists, who are not aware that electromagnetic velocity fields have an algebraic behavior inside conductors, which is completely different from the familiar exponential damping of electromagnetic wave fields. The ideas are of interest in connection with the electromagnetic shielding of systems from electromagnetic fields of passing charges and in connection with the Aharonov-Bohm effect where charged particles pass close to conducting solenoids. \textcopyright{} 1996 The American Physical Society.

Review of electromagnetic interference shielding materials fabricated by iron ingredients

DOI: 10.1039/C9NA00108E (Review Article) Nanoscale Adv., 2019, 1, 1640-1671Received 21st February 2019 , Accepted 1st April 2019First published on 1st April 2019Iron (Fe) and its counterparts, such as Fe2O3, Fe3O4, carbonyl iron and FeO, have attracted the attention of researchers during the past few years due to their bio-compatibility, bio-degradability and diverse applications in the field of medicines, electronics and energy; including water treatment, catalysis and electromagnetic wave interference shielding etc. In this review paper, we aimed to explore iron based materials for the prevention of electromagnetic interference (EMI) by means of both reflection and absorption processes, including the standard methods of synthesis of Fe-based materials along with the determination of EMI performance. It is customary that a proper combination of two dielectric-losses, i.e. electrical and magnetic losses, give excellent microwave absorption properties. Therefore, we focused on the different strategies of preparation of these iron based composites with dielectric carbon materials, polymers etc. Additionally, we explained their positive and negative aspects.Vineeta ShuklaVineeta Shukla was born in Uttar Pradesh, India, and received degrees from the University of C. S. J. M. Kanpur: Master of Philosophy in Physics (2012); Post-Graduation in Physics (2010); and Graduation in Physics and Mathematics (2007). She received two gold medals, the Sir C. V.

Currently, she is pursuing a PhD from the Indian Institute of Technology, Kharagpur, West Bengal, under the supervision of Dr Sanjeev Kumar Srivastava. Her research work includes the characterization and energy applications of carbon, polymer, metal and alloy materials. 1 Introduction 1.1 Electromagnetic interference (EMI) pollution In recent years, electromagnetic (EM) wave radiation in the gigahertz (GHz) range has been regarded as an alarming danger for commercial appliances, biological systems, high quality information technology and defense safety technologies, etc., because when these EM waves interfere with the input signal of the electronic devices, they create a noise that is known as electromagnetic interference (EMI) pollution. In general, EMI pollution could be considered as an undesirable outcome of modern engineering that has become grievous to human health, causing many diseases, e.g. headaches, sleeping disorders and trepidation. In communication devices (e.g. cell phones, computers, bluetooth devices, laptops), commercial appliances (i.e. microwave ovens, the design of microwave circuits) and the automotive industries (i.e. integrated electrical circuits), EMI pollution deteriorates the durability and proper functioning of electronic equipment. Therefore, this new kind of pollution has become a serious worldwide problem and its mitigation could be achieved only by use of EMI shielding materials.1 EMI shielding is defined in terms of the reflection and/or absorption of electromagnetic radiation by a material that acts as a barrier against the penetration of the radiation passing through the shielding materials. These materials prevent the transmission of EM radiation by reflection and/or absorption of the electromagnetic radiation or by suppressing the EM signals so that EM waves do not affect the functioning and durability of electronic equipment. In general, conductive materials like metals, owing to their high reflectivity, are widely used to isolate spaces or equipment from surrounding EM waves. This reflection shielding is based on the principle of the Faraday cage, in which inside the cage, space is completely impervious to external electric fields. On the other hand, absorption shielding is related to permeable materials i.e. magnetic materials. Accordingly, metallic conductors suffer a lack of flexibility, heaviness, and high costs. Meanwhile, ferromagnetic or ferrimagnetic materials have an intrinsic cut-off frequency, usually below the low GHz range, that hinders their use in EMI shielding over a broad GHz range. From this we concluded that, at present, we need to explore broadband shielding materials, those do not only work in the MHz range, but also neutralize EM waves in the GHz range. Most importantly, a lot of effort has been made in this direction; unfortunately to obtain simultaneously minimum reflection with a view to maximum absorption is still challenging task for practical applications.2–62 Scope of review Up to date, iron (Fe) based composites have been extensively studied and are most desirable composites in various applications. Ten years of data on Fe-containing composites, collected by Scopus and shown in Fig. 1(a and b), show how the demand for Fe composites has increased year-by-year in several fields of research such as materials science, engineering and many others. It is expected that this review article will benefit ongoing research pertaining to iron nanostructures in the field of EMI shielding, since reviews play a crucial role in continuing interest on current aspects of research in every academic field. Therefore, this review mainly focuses on the development of high performance EMI shielding materials, considering iron as one of the important ingredients. Fig. 1 (a) and (b) Scopus database (09/12/2018) for iron based research articles. 2.1 Mechanisms of shielding 2.1.1 Shielding efficiency in terms of reflection/absorption. Shielding efficiency (SET) could be defined as parameter that measures how well a material impedes the EM energy of a certain frequency when passing through it. Fig. 2a represents the possible interactions of EM waves with materials. When the EM waves fall on the front-face of the material then a certain part of the incident power (PI) is reflected (PR), while a certain part is absorbed and dissipated in form of energy, and the remaining part is transmitted (PT) through the shielding material. Therefore, three different processes namely reflection, absorption and multiple internal reflections contribute to the whole attenuation, corresponding to shielding effectiveness SER, SEA and SEM, respectively. (1)Here P, E and H refer to power and electric and magnetic field intensities while subscripts I, R and T represent the incident, reflected and transmitted components, respectively. Thus, SER refers to net reflection and SEA represents shielding due to absorption. Note that contributions from secondary reflections (output interface) in Fig. 2a and b occur in finite-dimensional media but in thicker slabs SEM can be neglected (Fig. 2c). Then, the equation takes the form Fig. 2 (a) Schematic diagram of incident, reflected and transmitted power and electro-magnetic field intensities when an EM wave is incident on a 3D material; (b and c) sources of reflection in a thin sample (input and output interfaces, Rin and Rout) and in a thick sample; (d–g) multiple reflections in the case of a porous structure, a hollow structure, a multiple shell structure and a solid sphere. 2.1.2 Reflection loss (SER). The primary mechanism of EMI shielding is reflection. Reflection loss (SER) is related to the relative impedance mismatching between the surface of the shielding material and the EM waves. The magnitude of the reflection loss can be given by (3)where σ is the total conductivity, f is the frequency, and μ is the relative permeability. It can be seen that SER is a function of the ratio of conductivity (σ) and permeability (μ) of the material i.e. SER ∝ (σ/μ). Thus, for a constant σ and μ, SER decreases with frequency. Therefore, materials must have mobile charge carriers (electrons or holes) for reflection of the EM radiation. 2.1.3 Absorption loss (SEA). A secondary mechanism of EMI shielding is absorption. As we know from the plane wave theory, the amplitude of the EM wave decreases exponentially inside the material as it passes through it. Thus, absorption loss results from ohmic losses and heating of the material due to the currents induced in the medium. For conductive materials, absorption loss (SEA) in decibels (dB) can be written as: (4)where d and α are the thickness and attenuation constant of the slab, respectively. The attenuation constant defines the extent at which the intensity of an EM wave is reduced when it passes through the material. It is clear that SEA depends on conductivity (σ), permeability (μ) and sample thickness (d). Such a dependency of SER/SEA on μ and σ indicates that in magnetic conducting metals, shielding is dominated by absorption rather than reflection. Moreover (5)where λ0 is the wavelength in vacuum and n is the refractive index, which is given by (εμ)1/2; in the case of nonmagnetic materials μ = 1. Hence, (6) It is clear from eqn (5) that high permittivity is particularly crucial for the enhancement of SEA, as well SR. 2.1.4 Multiple reflection (SEM). For thinner materials, radiation is trapped between two boundaries due to multiple reflection, i.e. EM waves reflect from the second boundary, come back to first boundary and are re-reflected from the first to second boundary, and so on, as shown in Fig. 2a. (7)where δ is the skin depth, defined as the thickness below the outer surface at which the incident field is attenuated to 1/e of its initial value, given by SEM depends on d and is closely related to absorption. Hence, multiple reflection plays an important role for porous structures and some definite geometries. For more visualization, Fig. 2d–g shows trapping/scattering of EM radiation by porous, hollow, multi-shell and solid structures. In this structure, a large surface area and a big vacant space excluding the solid structure gives more active sites for scattering and multiple reflection of electromagnetic waves. The hollow/porous structure shows unique properties, e.g., high surface area, disciplinable internal structures, low…
