Vector based higher-order 3D finite element simulation of microwave cavities
Finite elements (FE) for microwave device simulation are reviewed, with specific emphasis on vector elements. The FE analysis of microwave cavities, and the resulting generalised eigenvalue equation, is discussed. Results for two benchmark cavity analysis problems will be shown. Applications are briefly outlined. The paper concludes with an overview of current work, including sparse linear algebra and incorporating the FE code within the Advanced FEKO Code suite.
