Abstract
AbstractWe study the properties of left‐handed materials (LHMs) with the precise help of Sommerfeld integrals. First we argue by energy conservation principles that LHM has to be a backward‐wave material (BWM). Then we derive the equivalence of the loss and the Sommerfeld far‐field radiation conditions for a BWM. Next, we solve the realistic Sommerfeld problem of a point source over an LHM half‐space and an LHM slab. This analysis lends physical insight into the interaction of a point source field with an LHM, showing that super‐resolution is possible with an LHM slab. © 2004 Wiley Periodicals, Inc.
