Description

technical field [0001] The invention belongs to the technical field of microwave heat conversion, and in particular relates to a microwave heat conversion material, a carrier and a preparation method thereof. Background technique [0002] Microwave absorbing material, also known as radar absorbing material or radar stealth material, is a material that can absorb microwave and electromagnetic energy with less reflection and scattering. The basic principle of microwave absorption is to convert microwave energy into energy of other forms of motion through a certain physical mechanism, and convert it into heat energy through the dissipation of the motion. Microwave absorbing materials should have good microwave absorbing properties, that is, microwave absorptivity higher than the required threshold and a wide absorption frequency band. In addition, the microwave absorbing material should also have a small thickness and areal density. [0003] Microwave absorbing materials are ...
