The effect of anisotropy in multilayer superstrate-substrates on the propagation of a Gaussian pulse and a sinusoidally modulated Gaussian pulse in shielded microstrip lines (MLs) has been examined. Such multilayer superstrate-substrates are made of sapphire, ferrite and perhaps biaxially anisotropic materials, characterised by both tensorial permittivity and permeability. Mathematical treatments used were based on Galerkin's method in the spectral domain and fast Fourier transformation (FFT). Parametric studies were performed to show the effects of various diverse anisotropic occurrences in the superstrate-substrates on pulse distortion, including time delay, ringing and crosstalk between signal and sensing strips. It was shown that pulse distortion could be reduced effectively by combining different anisotropies in superstrates and substrates. [ABSTRACT FROM AUTHOR]
