Abstract The modulation of transport properties in ceramic‐based semiconductors can be used to optimize the electromagnetic response mechanism and performance. A semiconductor ceramic foam interlayer wall (SCFW) is designed by a physical vapor deposition method. structural SCFW composed semiconductor‐insulator‐semiconductor layers, incorporating composite system SiC, Al 4.8 Si 1.2 O 9.6 , 2 3 . Moreover, hierarchical network structure controlled pyrolysis‐deposition kinetic process. Electrons holes are transported through heterojunctions between SiC achieving effective charge relaxation. matrix provides lightweight (density 0.967 g cm −3 ), while determines excellent wave (EMW) absorption performance SCFW, with an bandwidth up 14.8 GHz under (minimum reflection loss RL min = −50.6 dB). has been proven exhibit corrosion resistance thermal insulation properties, conductivity 0.025 W m −1 K This study valuable insights into design dielectric property optimization nanocomposites, which leads strong polarization loss, opening new avenues for application EMW absorbers, ceramics.

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.
