Abstract :
The symmetrical condensed node TLM (transmission line matrix) method is used for S-matrix computation of microwave circuits. An edge coupled microstrip bandpass filter and a discontinuous ridge waveguide are analyzed as typical examples. The conditions which must be satisfied in S-parameter computation of such circuits are defined. The validity of the method is verified by comparison with results obtained by other numerical methods.<>
