The characteristic impedances of the slab line with an anisotropic dielectric having a tilted principal axis are numerically presented for sapphire and pyrolytic boron nitride. Moreover, an approximate formula of the impedance for a small wire is also presented by using the numerical data.

Exact equipotentials and lines of electric flux between two thin conducting plates in an anisotropic medium are theoretically presented by using an affine transformation and a conformal mapping technique.
