Electrodynamics of Metallic Photonic Crystals and the Problem of Left-Handed Materials
Electrodynamics of Metallic Photonic Crystals and the Problem of Left-Handed Materials
An analytical theory of low frequency electromagnetic waves in metallic photonic crystals with a small volume fraction of a metal is presented. The evidence for such waves has been obtained recently by experiments and computations. The cutoff frequency of these waves, omega(0), is studied. An analytical expression for the permittivity …
