负相速度介质研究综述
On mediums with negative phase velocity: a brief overview
摘要：
对反向相速度和功率流的几个问题进行了综述。提出了在各向同性电介质-磁介质中出现这种现象的必要条件。讨论了无像差透镜、均匀化方法和复杂介质的分支。
英文摘要：
Several issues relating to oppositely directed phase velocity and power flow are reviewed. A necessary condition for the occurrence of this phenomenon in isotropic dielectric-magnetic mediums is presented. Ramifications for aberration-free lenses, homogenization approaches, and complex mediums are discussed.
