Calculation and Fabrication of Photonic Crystal with Diamond Structure
摘要
Abstract
The plane wave propagation method was used to calculate the band gap width of photonic crystals (PCs)with diamond structure．When the lattice constant of the crystal is 8.5mm，the PC has a maximal band gap width of about 3．5GHz．In this case,the frequency of the band gap ranges from 15．3 to 18．7GHz．A computer solid model of a photonie crystal with diamond structure was designed．The epoxy PC was fabricated by stereolithography．The fabricated epoxy PC is 7．40mm×36．54mm×54．32mm in size,and the periodic numbers of the crystal in the x，y，and z directions are 2，4，and 6，respectively．The transmission of microwaves from 10 to 20GHz was measured along the(100)direction by an HP network analyzer.A band gap is formed in the range of 14．7～18．5GHz．The magnitude of the maximum attenuation is as large as-30dB at 17．3GHz,indicating that the fabricated structure works well as a photonic crystal．关键词
