Synthesis of material that absorbs electromagnetic waves in the 6G band

Phys Dot Org 07 Dec 2022
While conventional metals that absorb electromagnetic waves have reduced absorption capacity in high-frequency bands or have limitations in controlling frequency bands, epsilon iron oxide has high potential as a material for future communication parts due to its absorption capacity in the ultra-high frequency (30–200GHz) band.
