A Bionic Grooving All‐Cementitious‐Dielectric Metastructure with Unprecedented Wide‐Angle Broadband Electromagnetic Wave Absorption Properties

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 28, 2025

Abstract The absorption performance of electromagnetic (EM) wave absorbing materials deteriorates sharply at large incident angles, particularly angles exceeding 50°. To overcome this challenge, study proposes a bionic grooving all‐cementitious‐dielectric metastructure (ACDMS), yielding more than 34.6 GHz effective bandwidth ( EAB ) over 0°–60° without any agent. effects structural design, geometric parameters, and on the EM response are investigated by numerical simulations experimental characterizations. It is found that ACDMS enables multiple mechanisms under various including electric field redistribution, multi‐axis interference, surface excitation, diffraction/scattering pathways. Experimental results demonstrate 60° angle, even exceeds normal incidence, achieving relative 163%, ‐20 dB (99% absorption) 33.4 GHz, mean reflectivity −23.4 in 1–40 range. RCS simulation environmental testing across fluctuating humidity (40%–80%) temperature (10–220 °C) exposures underscore exceptional potential for practical applications harsh conditions. combination innovative mechanisms, adaptability convenient cement‐based manufacturing process establishes as promising candidate next‐generation absorbers.
