本文讨论了利用介电常数和磁导率实部为负的材料的平面平行板进行电磁辐射聚焦的研究。论证了系统极限可达分辨率受限的原因。从理论上和实验上证实了获得距离远小于波长的源分离像的可能性。
This Letter deals with the investigation of the electromagnetic radiation focusing using a plane-parallel plate of a material with negative real parts of the permittivity and permeability. The reasons are demonstrated for the restriction of the limiting attainable resolution of the system. The possibility of obtaining the separated images of sources the distance between which is much less than the wavelength is confirmed theoretically and experimentally.
