Optically Transparent Ka‐Band Absorber With Multi‐Fractal Rings and a Metal Mesh Ground Plane

Microwave and Optical Technology Letters, Volume 68, Issue 6, June 2026.
ABSTRACT An optically transparent absorber based on multi‐fractal ring resonators and a metal mesh ground plane is presented for Ka‐band applications. By merging multiple resonances, the proposed absorber maintains an absorption bandwidth from 25.8 to 31.1 GHz.
