Abstract
Photonic crystals with three-dimensional dielectric structures were fabricated to control terahertz waves effectively by using micro-stereolithography of a CAD/CAM process. The photonic crystals with a diamond structure composed of acrylic lattice with nanosized alumina particles were fabricated. Dense alumina structures were obtained by successive dewaxing and sintering in an air atmosphere. The electromagnetic wave properties of these samples were measured by using a terahertz spectroscopy device. The micro periodic structures exhibited perfect band gaps in the terahertz range. To control terahertz waves, micrometer sized electromagnetic devices for cavities, filters, and antennas will be necessary.
