The objective of this thesis is to develop a systematic framework for modeling electromagnetic wave propagation m RF and Microwave circuits with active and lumped components using S-parameters using the Finite-Difference Time-Domain (FDTD) approach, which was originally proposed by K. S. Yee in 1966. The mediod approximates the differentiation operators of the Maxwell equations with finite difference operators m time and space. This mediod is suitable for finding the approximate electric and magnetic field in a complex three dimensional stmcture in the time domain. The computer program developed in this thesis can be used to simulate various microwave circuits. This thesis provides the theoretical basis for the method, the details of the implementation on a computer and fmally the software itself.
