Abstract
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 complex 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.
Zusammenfassung
Exakte Netzwerkdarstellungen strahlender Strukturen sind nach wie vor ein ungelöstes Problem. In diesem Beitrag führen die Autoren das Konzept der Übergangsregion zur Herleitung einer Netzwerkdarstellung komplexer in den freien Raum strahlender Strukturen ein. Der Raum wird in einen oder mehrere Bereiche unterteilt, welche komplexe geometrische Strukturen enthalten und in eine Übergangsregion, welche durch eine sphärische Fläche gegen den äußeren Raum abgegrenzt ist. Durch Einführung des Übergangsbereichs wird ein größerer, mit Strukturen gefüllter sphärischer Bereich vermieden. Die theoretische Untersuchung der Herleitung einer äquivalenten Netzwerkdarstellung für den Übergangsbereich wird gegeben.
