中文摘要：
分析了平面电压波与一个夹在负折射率传输线媒质里的无损耗正折射率传输线媒质板的相互作用，在完全匹配的条件下，导出了这个介质板内外的电压分布。分析显示这个正折射率介质板也具有放大倏逝波的能力，结果提高了像的分辨率。为了展现这个正折射率介质板的完美成像功能，由单个Y方向的电流源所产生的电压解是被利用计算所有区域的电压幅度。数值仿真结果表明在源的电压波，包括传输波和倏逝波，能够在像点精确地重构，从而取得了完美成像。
英文摘要：
The plane voltage wave interaction with a lossless positive-refractive-index transmission line media slab surrounded by a negative-refractive-index transmission line media is analyzed. Under the full matching condition, the voltage distributions inside and outside of the slab are derived. The analysis reveals that the positive-refractive-index transmission line media slab is also capable of amplifying evanescent waves and as a result contributes to the image resolution. In order to demonstrate the perfect imaging capability of the slab, the solutions to voltage due to a single y-directed current source are utilized to computed voltage phase and magnitude in all regions. The numerical simulation shows that the voltage waves at the source, the propagating waves and the evanescent waves, can be exactly recon- structed at the images, and so the perfect image has been achieved.
