| Outline of Final Research Achievements |
The four-coordinated random network structure (PAD structure) with a photonic band gap (PBG), which we recently discovered, was fabricated with the size of a terahertz frequency region. First, the structure was fabricated by a laser beam lighography using acrylic resin containing alumina particles. Then, it was dewaxed at 600℃ and sintered at 1500℃. By these procedures, we finally obtained the PAD structure of alumina rods.
For the purpose of clarifying the formation mechanism of PBG in PAD, we constructed five- and six-coordinated random network structures on computer, and investigated numerically the PBG formations in them. No clear PBG formations were observed in these structures, indicating that the four-coordination in PAD plays an essential role in the PBG formation in PAD.
