摘要:
In this paper, a differential matrix operator technique is presented to simplify the formulation of boundary-value problems for open millimeter-wave integrated circuits (MIC's) which use anisotropic substrates. The spectral-domain method is applied to analyze the propagation characteristics of single and coupled microstrip lines printed on anisotropic substrates whose properties are described by both [epsilon] and [mu] tensors. In addition to considering the permittivity and permeability as a uniaxial or biaxial tensor, the effects of coordinate misalignment between the principal axes of [epsilon] and those of the structure in the transverse plane are also included. It is shown that the misalignment in [epsilon] and the presence of the [mu] tensor has a significant effect on the dispersive properties of these two structures.
