Pallavi Singhal

Abstract: In this paper, Green’s function and surface current density for planar structure has been calculated. The approach makes use of the popular and rigorously used spectral domain full wave analysis method in conjunction with method of moment as numerical analysis tool. In present approach, boundary conditions are applied at patch metallization, which leads to integral equation with the involvement of green’s function in spectral domain, which includes the effect of dielectric, conductor loss, surface wave modes and space wave radiation. By applying Galerkin’s moment method integral equation are transformed to linear set of equations. Entire domain basis function is used to improve the efficiency of the solution.

Keywords: Spectral domain full wave analysis, Green function, Galerkin’s moment method, Entire domain basis function, Surface current density.
