▲ [13p-1F-13] Advanced Microwave Antenna by Addition of Plasma Components (II)
Keywords:Plasma,Metamaterial,Microwave
After the theoretical analyses of Veselago in 60's on negative index material, and more recently researches including experimental results, we are able to create negative permittivity or permeability with a new material named as metamaterial. Furthermore, with anisotropic and spatially gradient refractive index, it is possible to achieve cloaking effect. Our proposal is to use the properties of plasma to obtain flexible cloaking. In particular, when we use such flexible cloaking effects for microwave antenna, we can reduce interferences among various propagating microwaves for telecommunication. To do that, we have generated a plasma cylinder and currently design installation of anisotropic negative permeability metamaterial. We demonstrated here the numerical method and initial results.
