Abstract :
The analysis of the dispersion characteristics of a transient signal in microstrip lines with anisotropic substrate is developed, with particular attention given to the effects of arbitrary orientations of the principal optical axis in anisotropic substrates. Numerical simulations are carried out for the propagation of transient signals (square or Gaussian pulses) along microstrips with anisotropic substrates. It is shown that the dispersion characteristics are substantially affected by the change of the orientation angle of the principal optical axis in the substrate.<>
