Abstract :
The general expressions of the finite difference method (FDM) and the finite difference time domain (FDTD) method are obtained for the quasi-static and full wave analysis, respectively. Maxwell´s equations are replaced by a set of finite difference equations which are eigenvalue problems in FDTD. The even and odd mode capacitances are presented for various ratios of the widths of microstrip line in the first layer to the thickness of the first layer in two-layer three-coupled microstrip lines on anisotropic substrates in the quasi-static analysis. The effective dielectric constants are obtained for frequency in the full wave analysis and are compared with those of spectral domain method
