Abstract:
An extended equivalent circuit (EEC) FDTD scheme is presented. This scheme exhibits high versatility, improved efficiency for the case of non-uniform meshes, and unconditional stability based on novel criteria for dispersive media and metamaterials. The EEC FDTD scheme applied to CRLH metamaterials may be regarded as the FDTD counterpart of the CRLH TLM scheme pioneered by Prof. W. J. R. Hoefer [1].
