Abstract

The invention discloses a reflection phase regulation and control single metasurface unit with programmable light sensitivity. The reflection phase regulation and control single metasurface unit comprises a surface metal structure layer, a middle dielectric plate layer and a bottom metal ground which are arranged in sequence. According to the invention, by controlling the bias voltages at the twoends of a PIN diode in the basic unit, the working state of the PIN diode is changed, and then the reflection phase is regulated and controlled; a photoresistor and the basic unit are integrated through a voltage control circuit; after the photoresistor detects a light source, the voltage at the two ends of the diode can be changed, so that the switching state of the diode can be correspondingly changed; the reflection phase can be controlled; and the reflection phase regulation and control basic unit with programmable light sensitivity is realized.

Description

technical field [0001] The invention belongs to the technical field of new artificial electromagnetic materials, in particular to a single metasurface unit with programmable light-sensitive reflection phase control in the microwave section. Background technique [0002] Metamaterials have unique electromagnetic properties that natural materials do not have. By artificially designing the structure of metamaterials in the sub-wavelength range, any equivalent electromagnetic parameters have been obtained to realize the control of electromagnetic waves. Metamaterials generally have a three-dimensional structure, so their complex structure, large volume, and high loss limit their applications. Therefore, the metasurface as a planar structure has gradually attracted widespread attention. Arranging the metasurface units with a special structure in a two-dimensional array can flexibly and effectively control the phase, amplitude, polarization, etc., and can be applied to imaging, st...
