Embodiment Construction

[0031] The embodiment of the present invention solves the technical problem of the polarization sensitivity of the reflective film in the prior art by providing a metamaterial reflective film and a manufacturing method thereof.

[0032] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0033] By including the metamaterial layer of the resonant unit of "circular symmetry structure and / or spherical symmetry structure" periodically distributed, when the incident electromagnetic wave is vertically incident on the metamaterial, it can have a consistent reflection effect on electromagnetic waves of different polarization states, thereby solving the problem The technical problem of the polarization sensitivity of the reflective film in the prior art.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjun...

Abstract

The invention discloses a metamaterial reflecting film and a preparation method thereof. By means of a metamaterial layer comprising resonant units which are periodically distributed and adopt "circular symmetric structures and / or spherical symmetric structures", when incident electromagnetic waves are vertically incident to a metamaterial, a consistent reflecting effect is achieved for the electromagnetic waves with different polarization states, so that the technical problem that the reflecting film is polarization-sensitive in the prior art is solved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a metamaterial reflective film and a manufacturing method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, optoelectronic devices are gradually developing in the direction of miniaturization, multi-function and integration. At present, UV mirrors have been widely used in UV lithography, astronomical observation, plasma diagnosis and other fields. At present, the traditional reflective film has the problem of polarization sensitivity, which greatly restricts its application. Contents of the invention [0003] The invention solves the technical problem of the polarization sensitivity of the reflective film in the prior art by providing a metamaterial reflective film and a manufacturing method thereof. [0004] The present invention provides a metamaterial reflective film, comprising: a substrate and a meta...
