A numerical scheme is presented to analyze plane periodic surfaces used in phased arrays and scattering applications. Use is made of the grounded dielectric‐slab Green function in formulating the electric field integral equation that is solved by iterative methods. Results comparing several iterative methods are presented as well as other results for reflection coefficients, active resistance, etc.

An efficient numerical method to analyze the electromagnetic field in presence of bodies of arbitrary shape and material is presented. The method has been applied to the problem of the field distribution in the far field of a mobile phone antenna near a head and a hand of a person. Resonant microwave circuits and scattering applications demonstrate the versatility and effectiveness of the present method. Other problems have also been studied, which can be conductors, dielectrics or and arbitrary combinations of both. The procedure is based on the surface and volume equivalence principles and a Galerkin method is used to solve the integral equations. I On partial leave from:
