It was excited by a small piezo chip in the cavity and the vibration of each point defect modes were detected by an optical interferometer. Point defect modes on 2D PC plate in vacuum  air and loaded with water were investigated theoretically and experimentally to make clear of Q factors  which are affected by inner attenuation  band gap effects and medium. The way to get high Q resonance has been found. It helps to design a new kind of resonator or sensor. 2011 IEEE.   Point defect states in two-dimensional phononic crystals 期刊论文  OAI收割 Physics Letters A, 2001, 卷号: 292, 期号: 3, 页码: 198-202 F. G.
