Abstract :
A metallic cylindrical resonator partially filled with double-negative (DNG) metamaterial with sector shape is analyzed in the frequency domain. The remaining part of the resonator is filled by a double-positive (DPS) medium. The structure results in a cylindrical resonator of finite length with a metamaterial wedge whose edge is on the cylinder axis. A line source excitation located in the DPS region is applied to investigate the properties of the structure by exciting the compatible modes of the structure. An exact analytical solution is obtained.
