Abstract

An exact analytical solution is obtained for the problem of finding the field of a linear electric current located near the interface between half-spaces filled with ordinary and perfectly matched double-negative media. To achieve this, a novel approach is introduced that, for the first time, enabled the correct analytic continuation of the function describing the field into the entire half-space filled with a double-negative medium. The analysis of this solution shows that the current source field, upon reaching the point of perfect focusing, passes through it and then moves off to infinity, rather than disappearing at that point, as claimed in earlier works.
