The design and experimental verification of metallodielectric photonic crystals (MDPC) that utilize simple, self-similar fractal metallic patch elements patterned on a thin dielectric substrate was presented. The element size and interelement spacing of cross-dipole and square-patch fractal elements were optimized using full-wave periodic method of moments modeling techniques. All structures fabricated based on these designs had two measured stopbands with greater than 10 dB attenuation positioned at wavelengths determined by element geometry, size and interelement spacing. The results show that this simple single layer fractal MDPC geometry will facilitate further scaling into the near-IR wavelength regime.
