摘要
双负材料(又称左手材料)是指介电常数和磁导率均为负的材料,双负材料具有与普通材料不同的电磁特性.双负材料在实验上取得了突破性的进展,各种特性逐渐被实现,文章对双负材料的原理和应用进行了研究.
Double-Negative Materials（Left-Hand Materials,LHM） are the electromagnetic materials in which dielectronic constant and the magnetic permeability are simultaneously negative.It has special electromagnetic characteristic different from that of common materials.The study on double negative materials has made breakthrough progress and various feature has been revealed.This article is a research on the principle and application of the double negative material.
