Microwave Absorbing Properties of Metallic Glass/Polymer Composites

: In this study, the microwave absorption characteristics of metallic glass / polymer composites were investigated. Electromagnetic wave absorption properties in the microwave spectrum are of particular importance to military applications. Radar absorbing materials have been studied for years and are of strategic importance for stealth technology. This work examined high magnetic permeability cobalt-based metallic glasses dispersed in epoxy matrices and measured the reflection loss behavior of the composites in the C-band and X-band spectrum. Results have shown that the metallic glass composites have good absorption in the region of interest due to the absorption properties of the glass particles and the graded structure of the composite.
