Abstract

The invention provides a multilayer paraffin composite phase transition material based adjustable two-dimensional optical invisible cloak. Paraffin composite phase transition material circular layers extend in the direction of an X and y axes layer by layer with the center of an x-y plane as an axis to form the adjustable two-dimensional optical invisible cloak; the solid-liquid state of paraffin composite phase transition materials in different circular layers can be controlled as so to allow various layers to correspond to different dielectric constants and magnetic conductivity coefficients, a two-dimensional dielectric constant and magnetic conductivity coefficient distribution which are desired by optical invisibility can be acquired, and then after light bypasses through a cloak zone, a light field resumes original distribution, the optical invisible function can be achieved, external light interference on an article in the center of the optical invisible cloak can be shielded, and external light field distribution cannot be affected. the solid-liquid state of the paraffin composite phase transition material in each circular layer can be controlled circularly, real-time on / off performance of the optical invisible cloak can be achieved, and the defect that the two-dimensional optical invisible cloak cannot allow circular on-off can be overcome.

Description

technical field

[0001] The invention relates to a method and device for realizing an adjustable two-dimensional optical invisibility cloak based on a multi-layer paraffin wax composite phase change material, which can be applied to the field of light field control. Background technique

[0002] In 2006, Document 1: "J.B.Pendry et al, SCIENCE, 2006(312): 1780" proposed for the first time that the use of anisotropic media can manipulate the propagation direction of light waves and realize the concept of optical cloaking, which has attracted widespread attention and has become an important field in the field of optics. research hotspots. In the same year, Document 2: "D.Schurig et al, SCIENCE, 2006(314): 977" verified the transverse electric wave two-dimensional metamaterial invisibility cloak for the first time in the microwave segment. In 2007, Document 3: "Cai et al, Nature Photonics, 2007(1): 224" proposed a transverse magnetic wave two-dimensional metamaterial invisibilit...
