Abstract

We have developed an efficient algorithm to solve the generalized microstrip line problem with multiple conductors on an inhomogeneous anisotropic substrate. The numerical results obtained using this technique agree well with previously published results. Two spatial interpolation schemes are used to compute the contribution from the off-diagonal components in the permittivity tensor. It is shown that the two-term interpolation scheme works just as well as the four-term interpolation scheme and yields a sparser matrix.
