摘要
通过引入缺陷和色散介质方法,调控光子的运动状态,研究一种压缩[A(BC)]m结构负折射率光子晶体的TE波和TM波的传输特性和色散特性,研究发现两种模的禁带特性随入射角和色散介质折射率的变化而变化,并且其带隙比普通光子晶体的大,而透射带要窄,这为高品质低损耗的谐振腔、微波天线、透射光栅、光波导等新器件的研制提供理论依据。
By introducing defects and dispersion medium, a kind of compression[ A（BC） ]^ m structure of photonic crystals is studied. It has negative refractive index. TE wave and TM wave propagation and hand gap characteristics are analyzed. It is shown that dispersion properties of the two modules change with the incident angle and refractive index of the dispersion medium,Its band gap is bigger than conventional photonic crystals,and the transmission band is more narrow. It provides a theoretical basis for the development of high quality low loss resonator, microwave antenna, transmission grating, optical waveguide devices.
