Problems solved by technology

However, the above methods have complex circuit structures and limited reconfigurability, especially the PIN diode switch only has two states of on and off, and most of the methods are not conducive to packaging and integration to make the system miniaturized, which makes reconfigurable electromagnetic metamaterials in high High-frequency millimeter wave to terahertz applications encounter challenges

Abstract

The invention provides a reconfigurable electromagnetic metamaterial. The metamaterial comprises a plurality of electromagnetic metamaterial units, each electromagnetic metamaterial unit comprises a first dielectric plate, a second dielectric plate, a metal reflection floor, a third dielectric plate and an air pressure switch which are sequentially arranged in the preset direction, a stepped emptygroove and a vertical through hole are formed in each second dielectric plate, and the bottom of each stepped empty groove is communicated with the corresponding vertical through hole; a liquid metalliquid storage tank is arranged in the third dielectric plate and is communicated with the vertical through hole in the second dielectric plate; the metal reflection floor is composed of a metal patch with a hole, and an opening is formed in the center of the metal reflection floor and communicated with the vertical through hole; and the air pressure switch is arranged at the bottom of the thirddielectric plate and is communicated with the liquid metal liquid storage tank in the third dielectric plate.

Description

technical field [0001] The invention belongs to the field of artificial electromagnetic materials, in particular to a reconfigurable electromagnetic metamaterial. Background technique [0002] Electromagnetic metamaterials are artificial materials with specific electromagnetic responses designed and formed by subwavelength metal / dielectric micro / nano structural units. Due to their special ability to manipulate electromagnetic waves, electromagnetic metamaterials have attracted extensive research interest in the past few decades. These electromagnetic wave control capabilities are not achievable by naturally occurring materials, and are usually achieved by the local control of phase, amplitude, and polarization of electromagnetic metamaterials. Electromagnetic metamaterials have been widely used, such as negative refraction, super imaging, stealth and radar, etc. [0003] Electromagnetic metamaterials allow efficient manipulation and guidance of electromagnetic waves in fre...
