摘要

实验研究了微波在具有折射率梯度的电场耦合超材料透镜中的传播。通过对超材料元件中单个参数的连续调谐，引入了超材料折射率的梯度。在平面波导中获得的实验场图表明，平面梯度折射率透镜可以用来准直来自线源的辐射，从而形成光束。

Electric-field-coupled metamaterials for microwave beam formation

Microwave propagation through an electric-field-coupled metamaterial lens with a refractive index gradient is experimentally investigated. A gradient in the refractive index of the metamaterial is introduced by continuous tuning of a single parameter in the metamaterial elements. Experimental field maps, acquired in a planar waveguide, demonstrate that the planar gradient index lens can be used to collimate radiation from a line source, thereby forming a beam.
