Abstract

The invention discloses a mercury-based temperature tunable electromagnetic metamaterial, which comprises a double-ring-shaped glass tube. A mercury column and two mercury balls are encapsulated in the double-ring-shaped glass tube. The mercury balls and the mercury column are encapsulated in the double-ring-shaped glass tube. The double-ring-shaped glass tube comprises a first ring-shaped glass tube and a second ring-shaped glass tube. The structure of the first ring-shaped glass tube and the structure of the second ring-shaped glass tube are the same. The first ring-shaped glass tube is communicated with the second ring-shaped glass tube. The positions of the two mercury balls are symmetrically arranged relative to the circle center of the double-ring-shaped glass tube. The diameter of each mercury ball ranges from 0.8 mm to 1.5 mm. The mercury column is of an arc structure, and the diameter of the mercury column ranges from 0. 05 mm to 0.15 mm. The initial arc length of the mercurycolumn ranges from 20 mm to 22 mm.

Description

technical field [0001] The invention belongs to the technical field of artificial electromagnetic structures, and in particular relates to a mercury-based temperature-tunable electromagnetic metamaterial and a manufacturing method. Background technique [0002] Electromagnetic metamaterial is a kind of electromagnetic structure artificially synthesized by sub-wavelength metal units, which has many strange electromagnetic properties that natural materials do not have. With the continuous and in-depth research on electromagnetic metamaterials, the untunable working frequency band has become the main technical bottleneck in the development of electromagnetic metamaterials. A variety of technologies have been proposed to solve the problem of non-tunable operating frequency bands of electromagnetic metamaterials, such as loading diodes, liquid crystals, ferrites, graphene, micro-electromechanical structures (MEMS), superconducting structures, etc. in conventional electromagnetic ...
