Abstract
An oblate semi-spheroidal cavity under a metal plane, partially filled with DPS material and DNG metamaterial is considered. The DPS and DNG regions are separated by a coordinate surface in the oblate spheroidal system. The primary source is a dipole located on the axis of symmetry of the structure and axially oriented. The field inside the cavity and the radiated field above the metal plane are found exactly. Numerical results are shown and discussed.
