Abstract :
This paper presents a stable broadband rational modeling approach through adaptive frequency sampling for full-wave simulation. It is based on vector fitting with improved robustness and enhanced efficiency for multiple ports. Examples have shown that the adaptive frequency sampling strategy can reduce the cost of expensive calls to the full-wave solver significantly
