The incorporation of static field solutions into the finite-difference time domain algorithm MMIC structures modelling

The authors demonstrate how the accuracy, speed, and flexibility of finite-difference time-domain (FDTD) analysis can be improved for the modeling of MMIC structures. Correction factors, obtained from the known behavior of static fields close to discontinuities, can be incorporated into the algorithm for application in the regions of high field variation where errors would otherwise occur. Application is made to both enclosed and open microstrip structures.>
