MEAN-FIELD THEORY OF 2-DIMENSIONAL METALLIC PHOTONIC CRYSTALS

Metallic photonic crystals have gaps starting from the null frequency. They can be used as antenna substrates. Using two computer codes base d on rigorous scattering theories, we investigate the properties of no ndoped and doped two-dimensional metallic photonic crystals. We show n umerically that such a structure can simulate a material that has a pl asmon frequency in the microwave domain. Below this frequency the crys tal is opaque and acts as a good reflector. These calculations confirm both a conjecture made by specialists in solid-state physics and math ematical considerations developed by specialists in limit analysis.
