Abstract: | The behavior of the leaky- and surface-wave modes supported by single- and double-layered grounded anisotropic dielectric structures is investigated. Simple low-frequency and high-frequency asymptotic formulas are derived for the wavenumbers. The effects of dielectric anisotropy and losses on the cutoff frequency of the TM and TE surface waves and on the H-plane radiation pattern of a leaky-wave antenna are examined |
