Abstract

We numerically investigate the electromagnetic field radiated by a line source within a perfect lens [Phys. Rev. Lett.85, 3966 (2000)] consisting of two orthogonal planes delimiting positive and negative index media. Use of a coordinate transformation [J. Phys. Condens Matter 15, 6345 (2003)] together with a well-adapted transfer-matrix method permits rigorous calculation of the vector field. We find that two negative corners combine to make a cavity that traps light along closed trajectories. Finally, we numerically show that the field presents some spatial oscillations with a period that is proportional to absorption sigma inside the negative materials as 1/ln sigma and that it is associated with an infinite density of states when sigma tends toward 0.
