Field computations and network representations for open electromagnetic structures

摘要

Rigorous network representations for radiating structures are still an open problem. In this contribution the concept of Transition Region for deriving such a network representation of compiex structures radiating into free-space is introduced. The space is divided into one or more computational domains which contain the complex geometrical features embedded into a transition region delimited by an outer spherical surface. The introduction of the transition region is expedient to avoid a large computational domain of spherical shape. A theoretical investigation of the computational procedures for deriving the transition region network representation is also presented.
