We studied the orbital angular momentum (OAM) wave scattering by a perfect electromagnetic conductor (PEMC) sphere using Mie Theory. The Vortex Electromagnetic (VEM) wave is well known with a definite amount of OAM. To obtain the OAM wave scattering from PEMC sphere, the conventional plane wave scattering from PEMC sphere expressions are modified by taking into account the characteristics of OAM waves. The unique properties of analytical expression of OAM fields are analyzed, and the scattered field coefficients in terms of incident field coefficients were obtained using boundary conditions. The comparison between conventional scattering for plane wave and OAM wave from PEMC sphere had been carried out. The presented work provides a theoretical insight for the calculation of Radar Cross Section (RCS) by metamaterial as PEMC sphere and identification applications of light carrying OAM in optical manipulation technology.
