Theoretical Study, Experimental Verification, and Real Applications of Metamaterials

Abstract:

Metamaterial is a hot topic nowadays, due to its great potential of improving the performance of RF/microwave/millimeter-wave wireless systems. In this talk, the recent progress will be reported on the metamaterial research conducted at Southeast University. The content includes the electromagnetic localization, open cavities, super waveguides, high-gain and high-directivity radiation, SAR enhancement, and super-resolution imaging, based on metamaterials. The experimental realizations will be demonstrated for open cavities, super waveguides, and evanescent-wave amplifications using circuit structures, and some device applications. Finally, this talk will introduce our recent results on resonant crystal bandgap metamaterials, a general theory for metamaterials, tunneling effects of metamaterials, and gradient-metamaterial lens.
