Scattering of electromagnetic plane wave by an impedance strip embedded in homogeneous isotropic chiral medium

Scattering of electromagnetic plane wave from a perfect electric conducting strip located in topological insulator medium

“…By solving above set of Equations (24)(25)(26)(27) weighting functions can be expressed in terms of unknown expansion coefficients. In order to expand these in terms of orthogonal set of Jacobi's polynomials (23); {u n ±1/2 (x a 2 ), v n ±1/2 (x a 2 )}, the trigonometric and Bessel functions are used in (20), (21). The expansion formulas are used to obtain the following set of matrix equation;…”

“…Infinite integrals which usually appear in the matrix equation are solved numerically (16)(17)(18)(19). Many investigators applied KP method to solve the electromagnetic scattering problems (20)(21)(22)(23)(24). The composition of material plays very important role in various fields of research especially in electromagnetic compatibility, terrain modelling and also in electromagnetic interface.…”

Scattering from metamaterial coated nihility sphere

“…Many researchers used metamaterials as filters, phase shifters, perfect reflectors, electromagnetic invisibility cloak, and wave guiders [1][2][3][4][5]. Some characteristic metamaterials which were being considered widely in already published work are plasma, Perfect Electromagnetic Conductor(PEMC), chiral [6], chiral nihility and split ring resonator (SRR) [7][8][9]. The nihility medium was considered as "the electromagnetically nilpotent" and has the most surprising impression in the field of electromagnetics and optics, in this material the relative permeability and relative permittivity both have zero magnitude.…”
