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

الملخص EN

Scattering of electromagnetic plane waves from a coated perfect electromagnetic conductor (PEMC) circular cylinder placed under perfect electric conducting (PEC) wide double wedge is presented.

It is assumed that the distance between the two wedges is large as compared to the wavelength.

Therefore, the field at an observation point can be considered to be composed of the incident field plus a response field from each of the edges of double wedge and the cylinder.

PEMC cylinder is taken to be infinite along its axis and has been coated with a double positive (DPS) or double negative (DNG) material.

The transmission coefficient and diffraction pattern of PEC wide double wedge in the presence of both coated and uncoated PEMC cylinder are studied.

Results of special cases for PEMC cylinder, compared with the published work, are found to be in fairly good agreement.

The techniques of Clemmow, and Karp and Russek have been used to investigate the transmission coefficient and diffraction pattern of the double wedge in the presence of both coated and un-coated PEMC circular cylinder.
