Abstract :
In this paper the mutual coupling between two apertures flush-mounted on a convex, perfectly conducting surface with variable curvature is analyzed by considering the surface ray propagating from the source to the receiver along the geodesic path. The problem-matched, surface magnetic Green´s function is presented here from two asymptotic formulations and one of them has been incorporated as a EM simulation software, uCAST. Numerical results for the isolation (S12) between two axial slots on a circular cone from uCAST, FEKO and measured data are presented. The initial comparison of the three shows very good agreement.
