## Abstract In this paper, we consider the field produced by a line current behind a layer of leftโ€handed material (LHM). Our purpose is to show that any slab of LHM (except the known case ฮต = โˆ’1 and ฮผ = โˆ’1) when is illuminated by a point source has infinite number of focal points with approximatel

## Abstract Effects of the frequencyโ€dependence of the permeability and permittivity of a leftโ€handed material (LHM), when used as one of the components of a Bragg reflector, are investigated. It is found that typical broad Bragg reflectivity peaks appear in the frequency range in which the materia

## Abstract We study the properties of leftโ€handed materials (LHMs) with the precise help of Sommerfeld integrals. First we argue by energy conservation principles that LHM has to be a backwardโ€wave material (BWM). Then we derive the equivalence of the loss and the Sommerfeld farโ€field radiation co
