Super-small resonant cavity

Abstract

This invention relates to a super-small resonator including a mum or a mm wave resonator with a negative permeability medium occupying the left space, in which, the resonant frequency of a resonator does not rely on the size of the resonator any more and one dimension structure is prior for the applied inverted medium (negative dielectric medium and negative permeability medium) according to the tunnel effect generated at the cross of the media.

technical field

[0001] The invention relates to a resonant cavity, in particular to an ultra-small micron-wave and millimeter-wave resonant cavity. Background technique

[0002] Anisotropic medium is a new type of artificial electromagnetic medium with periodic structure that appeared in the late 1990s. It has both negative permittivity and negative magnetic permeability, resulting in the electric field E of the electromagnetic wave propagating in the medium, The magnetic field H and the wave vector k form a left-handed system, instead of following the right-handed rule of conventional media, so it is also called an anisotropic medium. At present, with the deepening of people's understanding of heterotropic media, the connotation and extension of the concept of heterotropic media are constantly expanding. Anisotropic media does not only refer to media with negative permittivity and negative magnetic permeability at the same time. Metamedia with negative permittivity alone o...
