项目摘要

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. ***

INT 9732651Maradudin 这个美国-捷克研究项目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，将研究： 1) 电磁波在色散和吸附周期和随机中的传播无序系统和 2) 磁场对二维和三维周期系统光子能带结构的影响。研究人员还打算确定由嵌入缺陷引入的局域电磁模式的特性，这些缺陷以频率相关的介电函数为特征。他们合作的另一个组成部分将是二维系统中电磁波的安德森局域化，其特征是存在耗散时随机无序的介电函数。预计结果将揭示新的特征，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性质的基础知识的基础上。该材料研究项目通过使美国的领先专家能够实现推进科学知识的计划目标各国和中欧在共同感兴趣和能力强的领域结合互补人才并汇集研究资源。 ***
