Abstract

A method to describe barriers such as filters, cables, connectors etc. with circuits consisting of linear discrete components is presented. The circuit is constructed by viewing the barrier as a multiconductor transmission line for which the per-unit length parameters have to be determined. A developed two-dimensional finite difference program in which the cross-section is defined by drawing it using the CAD-like user interface computes these. For barriers that cannot be viewed as transmission lines a method for determining equivalent circuits outgoing from measured S-parameters has been developed. The derived models have been used in SPICE and validated by comparison with measurements
