Abstract-The design of resonators with degenerate magnetic and electric modes usually requires the ability to perturb one or both types of modes in order to induce alignment of magnetic and electric properties. In this paper perturbation theory is used to identify different types of inclusions that can be used to realize fundamentalmode degeneracy in a rectangular dielectric resonator and thus, can ultimately be used in the design of negative-index metamaterials. For reasons associated with fabrication in the infrared-frequency regime, rectangular resonator designs are of particular interest.

“…In such structures tuning is fulfilled due to the either electric field dependence of added component dielectric constant, conductance and/or capacitance or, as in the last case, due to its high frequency magnetic permeability adjustment with magnetic field. Other tuning techniques, with the assistance of electromechanical actuators, MEMS [10,12] or DR temperature change [13] are also known.…”

YIG is useful for dielectric resonator antenna (DRA) but its narrow size of frequency bandwidth (0.38-0.44 GHz), negatively influenced the DRA performance. An investigation on Ce doped YIG through the conventional solid-state reaction based on the Y 3-x Ce x Fe 5 O 12 (Ce x ; x = 0-1.5) system was carried out. Outside the range of 0.1 B x B 1.0 where maximum solid solution could be achieved, a new impure phase of CeFeO 3 (CIP) to YIG was detected. Ce affected the sample microstructure and reduced the grain size of YIG. For the DRA measurement, the addition of Ce enhanced the bandwidth efficiency (BW %) up to 11.16 %. The radiation patterns of all the samples indicated the omnidirectional characteristic, which suggested that the signal could be received by this dielectric antenna in various positions. Therefore, Ce doped YIG successfully enhanced the operating frequency of the antenna and was suitable for the X-band frequency range applications.
