Abstract

Systematic numerical methodology is proposed for accurate de-embedding of the port discontinuities in fullwave models of the unbounded multi-port circuits. The approach is based on the idea of short-open calibration (SOC). The latter being a numerical analog of the experimental TRL-technique provides a consistent removal of the feed networks in a wide range of frequencies. The treatment of multi-port topologies is achieved through the continuation of the original scalar SOC into the vector space. The new vector short-open calibration (VSOC) method provides a seamless interface with the integral equation based method of moments (MoM) solvers. Owing to the distributed nature of the microwave circuits the method allows for a substantial flexibility in the choice of the excitation mechanisms. Such commonly used MoM driving schemes as the ports locally backed up by the vertical wall, ungrounded-internal differential ports or via-mounted ports can be accurately de-embedded within the framework of the VSOC.
