Abstract
Photonic crystals are three- or lower-dimensional dielectric structure that exhibits overlapping stop bands in all directions. The focus of this work has been the design and characterization of a novel face-centered-cubic photonic crystal. The characterization was done in four parts. The first was a simple microwave network analyzer measurement where horn antennas were used transmit and receive CW microwave radiation. The second characterization was a direct time-domain characterization using photoconductively switched planar antennas to generate and detect short bursts of electromagnetic radiation. The third method of characterization was the high-power microwave characterization where the Sinus-6 was used as the source to generate high peak power pulses. The final characterization done was the use of infra-red thermal imaging to study the distribution of the scattered signal from a photonic crystal. Furthermore, the infrared thermal imaging was used to study the localized heating of the crystal due to high average power continuous wave excitation. Finally various applications of the three-dimensional photonic crystal emerged such as a UWB photonic crystal and photonic crystals as quasi-optical component for high-power microwave systems. This work lead to a number of ongoing collaborations including collaborations with Air Force Phillips Laboratory and MIT Lincoln Laboratory.
