Abstract

The invention discloses a reflective phase regulation regulated metasurface unit with programmable thermal perception. The reflective phase regulation regulated metasurface unit comprises a surface metal structure layer, a middle dielectric plate layer and a bottom metal ground which are arranged in sequence; the surface metal structure layer comprises a first polygonal metal patch, a second polygonal metal patch, a first metal wire and a second metal wire; and the first metal wire is connected with a frame of the first polygonal metal patch in parallel, the second metal wire is connected witha frame of the second polygonal metal patch in parallel, and the first polygonal metal patch and the second polygonal metal patch are symmetrically arranged up and down and are connected through a PIN diode. By controlling the voltage drop at the two ends of the PIN diode in the basic unit, the working state of the PIN diode is changed, and then the reflection phase is regulated and controlled. And the thermistor and the basic unit are integrated through the voltage control circuit, so that the distribution of a heat source detected by the thermistor is fed back by the on-off state of the diode, the reflection phase can be controlled, and the reflective phase regulation regulated basic unit with the programmable thermal perception is realized.

Description

technical field [0001] The invention belongs to the technical field of new artificial electromagnetic materials, and in particular relates to a reflection phase control metasurface unit with programmable thermal perception in the microwave section. Background technique [0002] As an artificial material with a periodic structure, metamaterials exhibit excellent electromagnetic control properties and achieve a high degree of freedom in material design, resulting in applications such as superlenses, computational imaging, stealth, and negative refraction. To further overcome the disadvantages of loss and profile, metasurfaces are considered as 2D versions of metamaterials. Compared with the bulk structure of metamaterials, metamaterials not only inherit the superior electromagnetic properties of metamaterials, but also are easy to process and apply. Among them, the encoding metasurface encodes each unit with different digital states, such as "0" and "1". Due to its efficient,...
