A metamaterial lens was designed based on a two-dimensional host transmission line network loaded with inductors and capacitors. The planar negative refractive index (NRI) periodic structure, consisting of a unit cell array with a concave side, works as a curved lens matched to free space operating at S-Band. An equivalent unit cell dispersion relation was developed to determine the transmission characteristics at the operating frequency range. The challenge in the metamaterial lens design is to increase the focal distance. In the simulated system, a high energy level throughout a focal region was observed in the whole frequency range. An equivalent bulky material is used as a resource to reduce computational effort.

基于加载有电感器和电容器的二维主机传输线网络设计了超材料透镜。平面负折射率 (NRI) 周期性结构由具有凹面的晶胞阵列组成，用作与在 S 波段工作的自由空间相匹配的曲面透镜。开发了等效的晶胞色散关系来确定工作频率范围内的传输特性。超材料透镜设计的挑战是增加焦距。在模拟系统中，在整个频率范围内观察到整个焦点区域的高能级。等效的大块材料用作资源以减少计算工作量。
