光子定域长度的测量张道中，胡炜，张有珑，李兆霖，程丙英，杨国桢（中国科学院物理研究所，北京１０００８０）两种不同折射率的物质交替排列形成的有序多层介质膜具有光子能隙，这已为人们熟知。对于一维无序系统的理论研究表明：光子在所有频率上都是定域的，即透射强...
MEASUREMENT OF PHOTONIC DOMAIN LENGTH ZHANG Duozhong, HU Wei, ZHANG Youlong, LI Zhaolin, CHENG Bingying, YANG Guozhen (Institute of Physics, Chinese Academy of Sciences, Beijing 100080) An ordered multi-layer dielectric film with two kinds of materials with alternating refractive indices has photons Energy gap, which is already well known. Theoretical studies on a one-dimensional disordered system show that photons are localized at all frequencies, ie ...
