FULL-WAVE ANALYSIS OF MICROWAVE MONOLITHIC CIRCUIT DEVICES USING A GENERALIZED YEE-ALGORITHM BASED ON AN UNSTRUCTURED GRID

A generalized Yee-algorithm is presented for the temporal full-wave an alysis of microwave monolithic integrated circuit (MMIC) devices, This algorithm has the significant advantage over the traditional Yee-algo rithm in that it is based on unstructured and irregular grids, Thus, u sing the generalized Yee-algorithm, MMIC devices that contain curved c onductors or complex geometries can be more accurately and convenientl y modeled using standard automatic grid generation techniques, The gen eralized Yee-algorithm is based on the time-marching solution of the d iscrete form of Maxwell's equations in their integral form, A correcti on scheme is introduced that is stable, maintains second-order accurac y, and maintains the divergenceless nature of the flux densities, Furt hermore, by structuring the algorithm as a series of sparse matrix-vec tor multiplications, the generalized Yee-algorithm can be efficiently implemented on vector or parallel high performance computers.
