Abstract

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