Quasi-TEM Analysis of Electromagnetic Parameters for Different Conducting Bodies

Abstract

Accurate and efficient computation of electromagnetic parameters for different conducting bodies represents an essential part of spacecraft modern integrated circuits. In this paper, we will illustrate modeling of inhomogeneous shielded rectangular, circular, triangular, and cylindrical transmission lines using the finite element method (FEM). We specifically determine the capacitance per unit length, inductance per unit length, and characteristic impedance of shielded transmission lines. Also, excellent agreement with some results obtained previously using the analytical formulas and methods, the approximate method, and numerical method is demonstrated.
