Analysis of S-parameters of Passive Microwave Devices Based on High-order Transfinite Element Method

This paper proposes a method for analyzing scattering parameters of passive microwave devices based on high-order transfinite element method. High-order hierarchical vector basis functions are utilized for purpose of improvement of the computing efficiency. The S-parameters can be obtained directly and precisely by a combination of the transfinite element method and finite element method. The results of numerical example demonstrate the correctness of the high-order transfinite element method by comparison with the results of the commercial software HFSS.
