摘要

在这项工作中，我们探讨了在微波条件下，当将1和4个堆叠的亚波长孔阵列作为叠加层时，商用喇叭天线的辐射方向图的改变。我们报告了当插入1层或4层时，e平面明显增强，而h平面几乎保持不变。我们将结果与穿孔结构的输出面上激发的电流密度以及由特殊传输超材料支持的反向传播联系起来。

Extraordinary Transmission surfaces as superstrate

In this work we explore in the microwave regime the modification of the radiation pattern of a commercial horn antenna when 1 and 4 stacked subwavelength hole arrays are placed as a superstrate. We report a clear enhancement of the E-plane while the H-plane remains almost unaltered when either 1 or 4 layers are inserted. We link the results with the current density excited in the output face of the perforated structure along with the backward propagation supported by the extraordinary transmission metamaterial.
