Abstract
Description
technical field
[0001] The invention relates to a phonon grating, which is mainly used in a superconducting medium resonant cavity phonon laser to achieve the purpose of modulating the phonon laser, and relates to the technical field of phonon transmission. Background technique
[0002] In June 2009, scientists from the University of Nottingham in the United Kingdom (The University of Nottingham) collaborated with colleagues from Ukraine to develop a new type of acoustic laser device and named it a phonon laser [3]. ), while the phonon laser is formed by the phonon vibrating by the sound wave. It is a laser in the acoustic sense, and strictly speaking, it should be called "exciting sound". The invention of phonon lasers has attracted the attention of many scientists, who believe that phonon lasers will have broad application prospects in the fields of computer computing, medical imaging and anti-terrorism security inspection.

Embodiment Construction
[0019] A phonon grating used in a superconducting dielectric resonator phonon laser provided by the invention is composed of a buffer layer, a medium layer and an impurity layer. Among them, the buffer layer is a phonon grating embedded in the output end of the superconducting dielectric resonator phonon laser. It is designed to fit the gap size of the phonon laser and prevent the wear of the dielectric layer. The dielectric layer is composed of two different materials alternately and repeatedly. The two parts of the dielectric An impurity layer is interposed between the layers, and the dielectric layer and the impurity layer are axially symmetrical as a whole.
[0020] The buffer layer of the phonon grating uses a ferrite material. The dielectric layer uses a phonon grating formed alternately by solids and fluids. The solids and fluids are respectively made of epoxy resin and water, and the thicknesses are 1 / 2 of the wavelength of sound waves in epoxy resin and water. times...
