| 摘 要： | 提出了离子型声子晶体的概念，发展了相应的理论：在实验上证实了离子型声子晶体中存在超晶格振动与电磁波的强烈耦合，观察到原先存在于离子晶体中的极化激元等长波光波行为；预言了一些可能的物理效应，离子型声子晶体超晶格振动和电磁波的耦合方程与黄昆方程在形式上完全一致，说明了超晶格与实际晶格在物理上的相似性。

| Abstract: | An ionic type phononic crystal(ITPC) composed of two piezoelectric media aligned periodically in a superlattice structure was studied theoretically and experimentally.Because of the coupling between vibrations of the superlattice and the electromagnetic waves,various long wavelength optical properties including microwave absorption and polariton modes that are related to ionic crystals were found in the ITPC.The fundamental equations that describe the coupling of the superlattice vibration and electromagnetic field are of the same type as Huang's equations,which means that the artificial crystal structure can be used to simulate microscopic physical processes in real crystals. |
