摘要

Laguerre-Gaussian (LG) beam scattering by a perfect electromagnetic conductor (PEMC) cylinder coated with a metamaterial is analyzed. In order to obtain the LG beam scattering from PEMC cylinder, the beam expressions are modified by considering the LG potential and plane wave scattering. The influence of beam parameters such as; the radial mode (p), azimuthal mode (l) , and beam waist radius (w(0)) is studied. The normalized bistatic radar cross section can be amplified or repressed using these parameters. A comparison of our results for p = 0 and l = 0 (fundamental Gaussian beam) by a PEMC coated cylinder is carried out and indicates good agreement for plane wave scattering.
