Description
Iftikhar ud Din, Daud Khan, and Tayeb Denidni design a flat patterned surface that soaks up microwaves in three separate bands, in a 2026 engineering study. The pattern pairs a square metal ring with two nested ten-sided resonators on a common circuit board material backed by metal. Target bands sit inside the S, C, and X ranges used by communication systems.
Simulations tuned the shape until absorption topped ninety-nine percent at each of the three peaks. Field maps and current patterns showed the coupled metal parts trapping energy inside the structure, where it fades as heat. Symmetry keeps performance nearly equal for either wave orientation, and absorption held steady for signals arriving at angles up to sixty degrees.
