Abstract
We report the fabrication and characterization of a novel photonic crystal in which multiple face-centered-cubic (fcc) crystals of different lattice constants are stacked in tandem. This results in a photonic stop band that is broadened well beyond that achievable with a single lattice periodicity. The sample reported here is comprised of two fcc crystals having photonic stop bands centered around 16.5 and 21.5 GHz, respectively. K-band feedhorns were used to transmit and receive radiation through the sample. A network analyzer was used to measure S21 and S11 between 14 and 26 GHz. The overall stop band is approximately the superposition of the individual stop bands of the component fcc crystals.
