Higher-Order Modelling of Media Interfaces for Enhanced FDTD Analysis of Microwave Circuits
The 1st and 2nd order accurate models of media interfaces are originally developed and incorporated into the FDTD method. Both models are shown to provide unambiguous results and increased fidelity of the FDTD method for inhomogeneous microwave circuits. They combine computational effectiveness of standard FDTD with accuracy equal or superior to that of nonorthogonal FDTD and FETD formulations. For practical problems the 1st order model proves satisfactory, the 2nd order model becomes feasible for coarse discretization.
