Abstract

A ring-shaped dipole resonant resonator relates to a resonator in wireless transmission, which solves the problem of vanadium dioxide (VO 2 When the electrical conductivity of ) increases, the ring-shaped dipole resonance strength of the overall structure is weakened. The present invention includes a plurality of resonance units arranged periodically, and each resonance unit includes a square metal ring and 4 vanadium dioxide strips; Two openings are symmetrically arranged on each side of the square metal ring, and the corresponding sides are divided into three sections, and the opening positions on each side are the same; 4 strips of vanadium dioxide are distributed in the square metal ring, and 4 two One end of the vanadium oxide strip is vertically connected to the middle of the four sides of the square metal ring, and the extension lines of the other ends of the four vanadium dioxide strips intersect at a point, which coincides with the center of the square metal ring 4 . The existence of the eight symmetrical openings of the present invention can reduce the influence of the resonance of the electric dipole and the magnetic dipole near the resonance frequency of the ring dipole, and avoid mutual interference.

Description

technical field [0001] The invention relates to a resonator in wireless transmission, in particular to a ring-shaped dipole resonant resonator. Background technique [0002] Toroidal resonance is electric resonance (including electric dipole resonance, electric quadrupole resonance, etc.) and magnetic resonance (including magnetic dipole resonance, magnetic quadrupole resonance, etc.) A third form of electromagnetic resonance, other than , was proposed by Zel'dovich in 1957 and later discovered in natural materials such as nuclear physics. Toroidal dipolar resonance is a typical form of toroidal resonance. Because of its high quality factor (Q value), it has wide application prospects in high quality factor sensors. However, the ring dipole resonance energy in natural materials is too small, which is often masked by strong electrical resonance or magnetic resonance, which increases the difficulty of detection and restricts the application of the ring resonance phenomenon. ...
