A theoretical investigation has been carried out to analyze the optical focusing electromagnetic field by a perfect electromagnetic conductor elliptical reflector in un-magnetized plasma environment. The presented analysis and formulations are general for any perfect conductor elliptical cylinder (PEC, PMC, or PEMC). The co-polarized and the cross-polarized components of the focal region electromagnetic field expressions have been obtained using Maslov’s method. The electromagnetic field behaviors at Caustic or focal point for the cases of PEMC, PEC (perfect electric conductor) and PMC (perfect magnetic conductor) elliptical reflector have been computed and compared. The behavior of the electromagnetic field behaviors at Caustic or focal point with the variation of the admittance parameter, plasma frequency and effective collision frequency for the co-polarized and the cross polarized fields is also investigated. 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.
