A Circuit Approach for the Electromagnetic Analysis of Inhomogeneous Cylindrical Structures

By Jose Antonio Marinho Brandao Faria
Progress In Electromagnetics Research B, Vol. 30, 223-238, 2011


An equivalent circuit, made of the chain connection of a number of T-type twoport networks, is proposed for the very accurate representation of the frequency-domain behavior of radially inhomogeneous solitary cylindrical structures, the individual two-port networks being made of frequency-independent R, L and C lumped elements. The accuracy of the model is dictated by the number of two-port networks, a number that increases with the frequency. The equivalent circuit approach is validated with the help of an application example concerning a special type of inhomogeneous tubular structures where exact closedform field solutions do exist.
