Perfectly calibrated internal ports in EM analysis of planar circuits

Abstract

Perfectly calibrated internal ports have recently been developed for high frequency electromagnetic analysis of planar circuits. This capability has never before been available. As such, microwave designers are only just now learning the value of such ports. This overview paper describes new and extremely efficient design methodologies that are now practical. For example, if properly prepared, an entire circuit can be EM (electromagnetically) analyzed once and the precise analysis of all subsequent modifications (tuning, tweaking) of the circuit provided essentially instantly. Another capability enabled by perfectly calibrated ports is compact model synthesis. These capabilities are illustrated with examples.
