Radar cross section (RCS) of perfect electromagnetic conductor (PEMC) cylinder by a Laguerre-Gaussian beam

Radar Cross Section (RCS) of perfect electromagnetic conductor (PEMC) cylinder using an incident Laguerre-Gaussian (LG) beam has been investigated. LG beam potential function is used to expand the incident and scattered electromagnetic (EM) field components. The co- and crosspolarized scattered field coefficients are determined by applying the PEMC boundary conditions at the interface i.e., r = a The obtained values for co- and cross-polarized scattered field components would be helpful to find out the scattered field distribution. A comparison of our results for PEMC and PMC for fundamental LG beam with beam mode p = 0, l = 0, i.e., LG(00) match with the gaussian beam scattering as witnessed in published work. The effects of OAM mode index (l), beam waist radius (w(0)), and PEMC cylinder radius on RCS have been analyzed.
