Liquid metal-based frequency reconfigurable metasurface, frequency regulation and control method and application

The invention relates to a frequency reconfigurable metasurface based on liquid metal, a frequency regulation and control method and application, and belongs to the field of electromagnetic metamaterials. Comprising a lower dielectric substrate, an upper dielectric cover plate and liquid metal, a circular through hole is etched in the upper-layer dielectric cover plate; a bow-tie-like micro-channel is etched on the lower dielectric substrate and is used for filling liquid metal; the upper and lower layers of media are bonded together; the liquid metal is driven by external force to flow in the micro-channel; liquid metal flows into the micro-channel through the circular through hole, and the frequency is adjustable by adjusting the liquid metal in the micro-channel. And compared with the prior art, the working frequency range is wider and the resonance depth is larger by adopting the liquid metal to regulate and control the frequency, so that the liquid metal can be used as a wave-absorbing material to realiz
