A compact 2D-FDTD scheme is enhanced with point-matched time domain finite element procedures to create a methodology for the dispersion analysis of arbitrarily shaped, lossless, multiconductor waveguiding systems in planar, multilayered, inhomogeneous anisotropic substrates. Additional improvements over the original compact 2D-FDTD method include: 1) A procedure for selecting the initial value for the field distributions in order to improve convergence; 2) A correlation integral type of spectral estimation. Comparisons with published results demonstrate the validity and accuracy of the associated computer program.
