ABSTRACT
This paper is devoted to the investigation of the electromagnetic scattering problems from infinite perfectly conducting cylinders with arbitrary cross-sections. The problems can be mathematically modeled as surface integral equations. Both the electric field integral equation (EFIE), magnetic field integral equation (MFIE) and their combined form are studied. An efficient computational technique based on the local radial point interpolation method is performed to investigate the models. Some test problems with various cross-sections have been analyzed to validate the capability of the proposed technique in calculating the current distribution induced on the scatterer and measuring the Radar Cross Section.
