Smart Processing in Materials Tectonics:Fabrication of Photonic Crystals for Terahertz Wave Control by Using Micor-stereolithography

摘要：

Photonic crystals with three-dimensional dielectric structures were fabricated in order 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 THz spectroscopy device. The micro periodic structures exhibited perfect band gaps in THz range. To control terahertz waves, micrometer sized electromagnetic devices for cavities, filters and antennas will be necessary.
