Abstract

In this work we introduce a novel near-field focusing plate able to provide sub-wavelength focusing in both directions, parallel to the plate, as well as for both polarizations of the illuminating plane wave at microwave frequencies. Two similar designs are proposed: the first one is made of a thick metallic plate, whereas the second one is made of a thin copper plate fabricated on top of a Rogers 5880 dielectric substrate. The focusing behavior of these structures is analyzed with Ansys HFSS and CST Microwave Studio full-wave simulators.

微波频率的双偏振近场聚焦板,提供二维亚波长聚焦
在这项工作中,我们介绍了一种新的近场聚焦板,能够在两个方向上提供亚波长聚焦,平行于板,以及在微波频率下照射平面波的两个偏振。提出了两种类似的设计:第一种是由厚金属板制成的,而第二种是由在罗杰斯5880电介质衬底上制作的薄铜板制成的。利用Ansys HFSS和CST Microwave Studio全波模拟器分析了这些结构的聚焦行为。
