Abstract

The invention relates to the field of electromagnetic metamaterials. In order to designed metamaterials to be more accurate and practical, the invention provides a metamaterial design method applied to a high-field magnetic resonance radio frequency coil. The design method can comprise the following steps that: the electromagnetic field simulation of a metamaterial periodic structure: using electromagnetic field simulation software to carry out structure design on the metamaterial periodic structure to enable the S parameter of the metamaterial to achieve magnetic resonance working frequency; the extraction of effective magnetic permeability: according to a simulated S21 parameter result, extracting the effective magnetic permeability of the metamaterial; and the manufacture of the real object of the metamaterial: manufacturing the designed metamaterial. The design method which is put forward by the invention has the main advantages: a simulation result is highly matched with the S21 measurement result of the manufactured real object of the metamaterial; a practically applied metamaterial size is taken as a simulation structure, a simulation result is more reliable, and therefore, the design method is more practical in a magnetic resonance field.

Description

technical field [0001] The present invention generally relates to the field of electromagnetic metamaterials, in particular to a metamaterial design method applied to high-field magnetic resonance radio frequency coils. Background technique [0002] The magnetic resonance system mainly includes magnets, spectrometers, gradient systems, radio frequency systems, image reconstruction systems, etc. The radio frequency system mainly uses radio frequency coils to excite and collect magnetic resonance signals. The performance of the RF coil directly affects the quality of the final image. With the development of science and technology and more and more interdisciplinary and integration, the combination of research results in different fields has gradually become a trend. Metamaterials are artificial composite electromagnetic materials with supernatural electromagnetic properties, which are composed of periodic distribution of unit structures. The application of metamaterials in ...
