Abstract

In this paper, a hybrid method of generalized transition matrix (GTM) and local physical optics (PO) is proposed. The GTM of a scatterer is defined uniquely to describe the relationship between the out-going fields and the incident fields on a specified reference surface. The PO algorithm is applied to obtain current distribution on the electrically large platform. Due to the locality principle, Fresnel zone is determined to reduce the unknowns on the platform analyzed by PO method. The computational efficiency can be improved comparing with conventional method. Numerical examples will be shown to demonstrate the feasibility of the hybrid method.
