U.S. Czech Materials Research on Electromagnetic Waves in Periodic and Randomly Disordered Systems and Magnetic Field Effects on Photonic Band Structures

这个由加州大学欧文分校的Alexei Maradudin博士和捷克无线电工程与电子研究所的Vladimir Kuzmiak博士合作的美国-捷克研究项目将研究：1)电磁波在色散和吸附周期性和随机无序系统中的传播；2)磁场对二维和三维周期性系统的光子带结构的影响。研究人员还打算确定由频率相关介电函数特征的嵌入缺陷引入的局域电磁模式的性质。他们合作努力的另一个组成部分将以二维系统中的电磁波的安德森定位为特征，该系统以存在耗散的随机无序介电函数为特征。结果有望揭示新的特征，扩大光子晶体的潜在应用，并建立在我们对更复杂结构内电磁场本质的基本知识的基础上。该材料研究项目实现了推进科学知识的计划目标，使美国和中欧的顶尖专家能够结合互补的人才，并在共同感兴趣和能力强的领域汇集研究资源。＊＊＊

INT 9732651MaradudinThis U.S.-Czech research project between Dr. Alexei Maradudin of the University of California-Irvine and Dr. Vladimir Kuzmiak of the Czech Institute of Radio Engineering and Electronics will examine: 1) the propagation of electromagnetic waves in dispersive and adsorptive periodic and randomly disordered systems and 2) magnetic field effects on photonic band structures of two- and three-dimensional periodic systems. The researchers also intend to determine the properties of localized electromagnetic modes introduced by embedded defects characterized by frequency-dependent dielectric functions. An additional component of their cooperative effort will feature the Anderson localization of electromagnetic waves in two-dimensional systems characterized by a randomly disordered dielectric function in the presence of dissipation. Results are expected to reveal new features that expand potential applications for photonic crystals and build upon our fundamental knowledge of the nature of electromagnetic fields inside more complex structures.This materials research project fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Central Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ***
