Microwave Power Absorption Mechanism of Metallic Powders

Microwave processing of metallic powders, both in multimode and single-mode cavity, has attracted wide interest. However, the mechanism of interaction between microwaves and metal powders is not yet very well understood. In this paper, the microwave power absorption mechanism in metallic powders has been systematically studied. For this, mixtures of copper and alumina powders have been processed i...
