Application of TLCODE method to parallel transmission lines

In this paper the circuit modeling of parallel transmission lines by TLCODE method is introduced. The formula of interface voltage between parallel transmission lines and the series transmission line, necessary for TLCODE, is deduced, and a PSPICE circuit with four parallel transmission lines is constructed. The comparison of calculated results between TLCODE and PSPICE shows that the modeling of parallel transmission lines by TLCODE method is valid.
