Exploring the scattering characteristics of twisted vortex electromagnetic light waves with a PEMC sphere in isotropic plasma

Vortex beams (VBs) carrying orbital angular momentum (OAM) have recently fascinated a lot of consideration. The inclusion of OAM in vortex beams makes them exceptionally versatile for several applications. So, inspired by the exciting uses of vortex electromagnetic waves (VEMWs), this work examines how twisted light waves like VEMWs interact with a metamaterial perfect electromagnetic conductor (PEMC) sphere in an isotropic plasma medium. Influences of configuration parameters of an isotropic plasma, i.e., plasma density and effective collision frequency, on the scattered field distributions of VEMWs are examined numerically. The study's results might be useful for understanding how different metamaterials interact with VEMWs when subjected to isotropic plasma.
