On mediums with negative phase velocity: a brief overview
arXiv:physics/0205027 · doi:10.1117/12.473003
Abstract
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.
