Abstract
Three-dimensional photonic-bandgap crystals are used to design and fabricat e uniquely directional sources and receivers. By utilizing the resonances o f a Fabry-Perot cavity formed with photonic-bandgap crystals, we were able to create exceptionally directional sources by placing the sources within s uch a cavity. Very good agreement between finite-difference time-domain cal culations and the experiment is obtained. Radiation patterns with half-powe r beam widths of less than 12 degrees were obtained.
