The scattering of electromagnetic waves by a perfect electromagnetic conductor (PEMC) sphere coated with a plasma isotropic material is studied in this paper. The extended classical theory of scattering is used to physically model the scattering problem. All the fields are expanded in terms of spherical vector wave functions (SVWFs), and then scattering matrices are obtained by applying the boundary conditions at each interface i.e., free space/ plasma and plasma/ PEMC. The presented analysis and formulations are general for any perfect conductor cylinder (PEC, PMC, or PEMC) with general isotropic material coatings. After that, the Co and Cross-polarized scattering coefficients are numerically computed and used to calculate the radar cross section (RCS). The influence of plasma parameters i.e., plasma density (n) and effective collision frequency (v) on RCS is analyzed and reported that radar cross section can be controlled by choosing the appropriate plasma parameters. It is also concluded that plasma coating can be used for target protection.The comparisons of the computed results of the presented formulations with the published results of some special cases confirm the accuracy of the presented analysis..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
