| 摘 要： | 利Pendry提出的坐标变换方法，研究了负折射材料构成的旋转椭球体、旋转抛物体和双球面系统中的光学补偿效应，发现系统的介电常数和磁导率为某一定值，该系统就具有相应的光学补偿效应，即从系统中某一点所发出的光线可传播至系统中另一点，该点的光场和光源完全一致．特别是双球面系统，其介电常数和磁导率可设计为一个标量，大大降低了技术上的难度，从而可能应用于某些实际光学系统．

| Abstract: | In this paper,we have investigated the optical cancellation effect in rotating ellipsoid system,revolution parapoloid system,and bispherical system by coordinate transformation method.We found that the system would take on cancellation effect provided we design the dielectric constant and permeability correctly,that is,the light emission from one point of the system could propagate to the other point where the field of the light is the same as the field of the source.Especially,for bispherical system,the di... |
