Scattering from an Arbitrarily Incident Plane Wave by a PEMC Elliptic Cylinder Confocally Coated with a Chiral Material
Keywords:
Bistatic, chiral, elliptic cylinder, Mathieu functions, PEMCAbstract
An analytic solution to the problem of scattering of a plane electromagnetic wave by a chirally coated elliptic cylinder defined by PECM boundary condition has been obtained by expanding the different electromagnetic fields in terms of appropriate elliptic wave functions and a set of expansion coefficients. The expansion coefficients associated with the transmitted field inside the coating as well as the scattered field outside the coating are unknown and will be obtained by applying the boundary conditions at various layers. Numerical results have been presented graphically to show the effects of chiral and PEMC materials simultaneously on the bistatic width of scattering from coated elliptic cylinder.
