Wideband and low loss metamaterials for microwave and RF applications: Fast algorithm and antenna design

Metamaterials represent a new class of artificial materials which exhibit special properties of negative refractive index (NRI). Over the past several years, the metamaterials research has been intensively conducted for the microwave and radio frequency (RF) applications. However, difficulties were faced and are still being faced right now in the developments of (1) efficient solvers and/or tools for metamaterial designs; and (2) design and fabrications of metamaterials of low loss and broad frequency bandwidth. Although in optical region, these are not key issues, they are in fact the key issues of the metamaterial research in microwave and RF region. This talk is split into two major parts: (1) the first is to look into the EM wave properties in metamaterials and to develop an efficient solvers for their designs; and (2) the second is to try to design the metamaterials for antenna applications.
