Paper Abstract

Fabry-Perot type resonances have been observed in the stop band of a metallodielectric photonic crystal at Ku band microwave frequencies. The metallodielectric photonic crystal has a face centered cubic Bravais lattice structure. The lattice constant is 15 mm. Metallic spheres with 6.35 mm diameter are placed at the lattice sites. In the transmission measurements, the metallodielectric photonic crystal displayed a directional bandgap with a lower band edge of 13.0 GHz, an upper band edge of 21.5 GHz, and a center frequency of 17.25 GHz, corresponding to a stop bandwidth center frequency ratio of 50%. The maximum rejection at the band center is 35 dB, corresponding to a 7 dB per unit cell rejection ratio. The Fabry-Perot type resonance has a quality factor of 200, with a maximum transmission peak of -5 dB.
