Scattering of Electromagnetic Plane Waves from a Coated PEMC Circular Cylinder Placed under PEC Wide Double Wedge

摘要

Scattering of electromagnetic plane waves from a coated perfect electromagnetic conductor (PEMC) circularcylinder placed under perfect electric conducting (PEC) wide double wedge is presented. It is assumed thatthe distance between the two wedges is large as compared to the wavelength. Therefore, the field at anobservation point can be considered to be composed of the incident field plus a response field from each ofthe edges of double wedge and the cylinder. PEMC cylinder is taken to be infinite along its axis and hasbeen coated with a double positive (DPS) or double negative (DNG) material. The transmission coefficientand diffraction pattern of PEC wide double wedge in the presence of both coated and uncoated PEMCcylinder are studied. Results of special cases for PEMC cylinder, compared with the published work, arefound to be in fairly good agreement. The techniques of Clemmow, and Karp and Russek have been used toinvestigate the transmission coefficient and diffraction pattern of the double wedge in the presence of bothcoated and un-coated PEMC circular cylinder.
