Title:
METHOD FOR IMPROVING MICROWAVE TREATMENT UNIFORMITY BY USING ELECTROMAGNETIC METAMATERIALS
Document Type and Number:
WIPO Patent Application WO/2023/197906
Kind Code:
A1
Abstract:
Disclosed a method for improving microwave treatment uniformity by using electromagnetic metamaterials, comprising: firstly, selecting a variety of electromagnetic metamaterials which generate outgoing waves having phase differences after the same electromagnetic waves are incident thereon; then, splicing the different electromagnetic metamaterials; next, placing a combined electromagnetic metamaterial in a microwave cavity and moving the combined electromagnetic metamaterial, recording a change rule of electromagnetic power density distribution in the microwave cavity, and selecting a position point of the combined electromagnetic metamaterial having good electromagnetic power density space distribution complementarity; and finally, designing the movement velocity and residence time of the combined electromagnetic metamaterial according to the intensity distribution of the electromagnetic power density in the cavity corresponding to the selected position point. Therefore, the average electromagnetic power space distribution uniformity in the cavity is significantly improved, and the average microwave power absorbed by all parts of the treated material is roughly equal, thereby achieving the purpose of improving the microwave treatment uniformity.
