Problems solved by technology

But generally speaking, once these conventional control devices are designed and produced, the control methods are relatively single and cumbersome, and the frequency bands that can be controlled are relatively limited, which seriously limits the application and development of terahertz technology. Therefore, designing a multi-channel Regulation and multi-band resonators are of great significance

Embodiment 1

[0034] In this embodiment, the structure and the shape of each component of the force / electrical dual tunable multi-band reflective polarization insensitive resonator are as described above, and thus will not be repeated here. However, the specific parameters of each component are as follows: the resonant ring air slot 3, the vertical rectangular air slot 4, the horizontal rectangular air slot 5, the vertical U-shaped air slot 6, and the horizontal U-shaped air slot 7 are filled with air. The outer side length of the resonator ring air groove 3 is 120 μm, the inner side length is 110 μm, and the thickness is 2 μm. The vertical rectangular air grooves 4 and the horizontal rectangular air grooves 5 are equal in size, with a length of 150 μm, a width of 20 μm, and a thickness of 2 μm. The vertical U-shaped air grooves 6 and the horizontal U-shaped air grooves 7 are equal in size. The vertical U-shaped air slot 6 has a thickness of 2 μm, the vertical rectangle has a length of 150...

Abstract

The invention discloses a force / electricity double adjustable multi-band reflective polarization insensitive resonator. It includes N×N structural units arranged periodically on a plane; each structural unit includes a two-dimensional graphene nanolayer, a metal layer and a flexible dielectric layer, wherein the two-dimensional graphene nanolayer is on the top layer, and the two-dimensional graphene nanolayer The lower layer is a metal layer, and the lower layer of the metal layer is a flexible dielectric layer; the metal layer is provided with resonant ring air slots, vertical rectangular air slots, horizontal rectangular air slots, vertical U-shaped air slots, and horizontal U-shaped air slots. Since the resonant device uses a flexible dielectric layer, the deformation of the device is realized by applying an external force to the device, thereby achieving the regulation of the overall resonance characteristics of the device. The top layer of the resonance device is a two-dimensional graphene nano-layer, and the chemical potential of the two-dimensional graphene nano-layer is changed by electrification to control the reflectivity at the resonance point of the device.

Description

technical field [0001] The invention relates to the technical field of terahertz wave applications, in particular to a force / electricity dual-adjustable multi-band reflective polarization insensitive resonator. Background technique [0002] Terahertz waves refer to electromagnetic waves with frequencies in the range of 0.1 to 10 THz and corresponding wavelengths in the range of 3000 to 30 μm, electromagnetic radiation between microwave and infrared bands, and occupy a very special position in the electromagnetic spectrum. In recent years, as terahertz technology has attracted extensive attention in the fields of high-speed communication, imaging, and radar, various terahertz switches, terahertz filters, and terahertz modulators have been developed. However, in general, once these conventional control devices are designed and produced, the control methods are relatively simple and cumbersome, and the frequency bands that can be regulated are relatively limited, which seriousl...
