摘要光学斗篷隐身是指通过变换光学的理论来对隐身“斗篷“的材质的参数进行设计研究，亦或者借由简单的几何光学理论搭建合出合适的光路，使得光线能够在传播过程中，绕过斗篷区域沿原路前进以营造出一种的隐身效果。43619

本文通过对光学斗篷隐身技术的研究，主要内容包括：

1.对国内外关于光学隐身的理论基础——变换光学以及对光学隐身斗篷的发展过程进行了背景研究以及现状介绍。

2.详细讨论了坐标变换理论，给出了理论的详细证明过程。

3.通过Mie理论分析较为全面和正确的证明了柱形和球形的电磁斗篷。

    4.基于变换光学可以造出没有相位和振幅变化的隐身斗篷，但是在可见光波段难以实现。由于人眼对相位变换不敏感，在不考虑相位的要求下，在无源线性折射和反射性因素的基础上制作出了两种非常简单的隐身斗篷装置。

Title  Research  on  invisibility  cloaks  about  optical trainsformation

Abstract

The invisibility cloak of optics is defined by the theory of transformation optics "cloak" material parameters on stealth were study design or borrowed by simple geometrical optics theory to build a suitable optical path, allowing the light to be able to in the communication process, by passing the Cape region along the way forward to create a stealth effect.

In this paper, the main contents of the study of the optical cloak stealth technology are:

1.based on the theory of optical stealth at home and abroad, this paper introduces the background and the current situation of the transformation of Optics and the development process of the cloak of invisibility.

2.the theory of coordinate transformation is discussed in detail, and the theoretical analysis of the cylindrical and spherical electromagnetic cloak is proved by Mie theory.

3.Based on transformation optics can create no phase and amplitude of the invisibility cloak, but in the visible light wave band is difficult to achieve, because the human eye is not sensitive to phase transformation, do not consider the phase, on the basis of passive linear refraction and reflection factor produced two very simple invisibility cloaking device.
