电介质小球的二维周期性排列胡炜，杨君慧，李兆霖，张道中，杨国桢（中国科学院物理研究所，北京１０００５０）将折射率反差很大的两种电介质材料交替地周期排列成具有光子能带结构的材料是目前光物理研究的热门课题之一。对它的研究不仅能拓宽量子电子学的新领域，如Ｓ... Two-dimensional periodic arrangement of dielectric pellets HU Wei, YANG Jun-hui, LI Zhaolin, ZHANG Dao-zhong, YANG Guo-zhen (Institute of Physics, Chinese Academy of Sciences, Beijing 100050) Two kinds of dielectric materials with large contrast reflectivity are alternately periodically arranged to have photonic energy bands The structure of materials is one of the hot topics in photophysics. Its research can not only broaden the new field of quantum electronics, such as S ...
