Modeling of Lossy and Dispersive Media with Higher Order FDTD Schemes

2 MODELING OF LOSSY AND DISPERSIVE MEDIA WITH HIGHER ORDER FDTD SCHEMES 

The incorporation of lossy and frequency-dependent materials in the production of modern devices, such as patch antennas, waveguides, or integrated circuits, has become a topic of intensive studies due to several attractive properties. Toward this direction, Yee s algorithm has already received the suitable modifications to cope with lossy [1-4] and dispersive configurations [5-19]. Given the competence of higher order schemes in material simulation, a possible
