Ogival Resonator Half-filled Half filled With DNG Metamaterial
Abstract: A metallic cylindrical cavity with planar bases and with side walls consisting of two equal concave parabolic cylinders having the same focal line is considered. The symmetry plane through the focal line and the intersecting lines of the parabolic cylinderss divides the resonator into two equal volumes, one filled with double positive material and the other with double negative antiisorefractive metamaterial. The exact electromagnetic field inside the resonator is obtained.
