“…The reason for this is that the input impedance of structure has a smoother response when the plasma substrates are utilized. The previous experimental demonstrations [43,44] allow the plasma parameters employed in the present study to be freely chosen in the validity ranges of 1 × 10 10 < ω p < 6 × 10 10 and 1 × 10 6 < ν p < 1 × 10 11 . By properly adjusting the parameters, the metasurfaces are designed to exhibit a broadband impedance mismatch in the upper frequency range, and the plasma medium parameters are adjusted so that a wideband attenuation in the lower frequency region is guaranteed.…”

“…Owing to the reconfigurable operation, i.e., ON or OFF, plasma has been found as an especial placement between other natural materials, especially in wave manipulation engineering [34,35]. More recently, according to the interesting features enabled by the plasma mediums, different combinations with the other artificial structures have been reported for them, leading to substantial improvements in the overall performances [36][37][38][39]. For instance, Yuan et al designed a multilayer radar-absorbing structure with plasma-and radar-absorbing material (RAM) to investigate the stealth mechanisms of a multilayer absorber [36].…”

Abstract-For the first time, the concept of combinational use of subwavelength metasurfaces and plasma media is introduced in this paper for being utilized in practical radio frequency (RF) shielding applications. Using an equivalent circuit model, it is demonstrated that the simultaneous use of the lossy characteristic and special dispersion of plasma in low-frequency regime and the transmission zeros provided by spatially homogeneous metasurfaces in the upper frequency band results in superior shielding performances. The designed coating layer has an ultra-thin profile while exhibiting a super wide reject band ranging from 1 to 20 GHz (|S 21 | < −10 dB). A fair comparison is also performed to elucidate that the proposed plasma-metasurface composite (PMC) shield outperforms the previously reported RF shielding FSSs in both bandwidth and thickness. The numerical results show that while maintaining a low profile, the shielding bandwidth of the designed PMC can be set to surprisingly include all the UHF, L, S, C, X, Ku, and K bands. Moreover, the designed coating layer provides a stable and polarization-insensitive reject band for different incident wave angles up to 45 • . These superior performances, as well as the shielding tunability enabled by plasma, confirm the promising capabilities of PMC structures for various applications.

“…Liu and Behdad demonstrated that the problem of EM wave tunneling through cascaded epsilon-negative metamaterial and double positive material barrier structure is analogous to the classical problem of coupled-resonator microwave filters [5]. In recent studies on multilayered structures, researchers have been using integer dimension substrate [1][2][3][4][5][6]21]; this means that the effect of dimension on the characteristics of structures was not considered. This research has been carried out to further include the parameter of dimension and see its effect on the characteristics of the multilayered structures, because not every object that exists in this universe can be modeled with Euclidean geometry (integer dimension).…”

Abstract-This paper discusses the electromagnetic characteristics of a stratified metamaterial structure placed in fractional dimension space. Reflection and transmission coefficients for plane wave incident on multilayered structure in D-dimensional space are computed. Transfer matrix method is used to study the behaviour of different planer multilayered periodic metamaterial structures. The results are compared for integer and fractal dimensional spaces for both the cases of normal and oblique incidences. Classical results are recovered for integer dimensions. This work provides solution for examining the electromagnetic fields and waves in multilayered structures at fractal interfaces.

Magnetic line source diffraction by a conductive half‐plane in an anisotropic plasma

An integral theory that is associated with the scattered fields is considered for the solution of H-polarized line source diffraction by a conductive half-plane, which is surrounded by an anisotropic plasma. As the anisotropy does not affect an E-polarized incident wave, only one polarization case is considered. The cold plasma medium is characterized by the dielectric tensor. The constant external magnetic field producing the anisotropy in a cold plasma is applied parallel to the edge of the half-plane. The total, scattered, and diffracted waves are derived in terms of the Fresnel functions. Therefore, finite magnitude values at the transition boundaries are obtained. The wave behaviours are investigated numerically for different quantities of the medium.
