Rare Metals, EarlyView.ABSTRACT The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high‐performance electromagnetic wave (EMW) absorbing materials. Although carbide‐based materials are promising because of their conductive and polarization losses, existing single ...

Advanced Science, Volume 13, Issue 7, 3 February 2026.An epsilon‐negative response of up to 100000 in the radio frequency band is achieved by creating a metacomposite system with graphene/iron (III) oxide as the main body. The magnetic metacomposites are just like the mythical creature Qiongqi in Chinese mythology, capable of swallowing electromagnetic wave pollution that falls from the sky.

Frequency Selective Rasorber With Low Insertion Loss and Ultra‐Broadband Scattering Reduction
Advanced Physics Research, Volume 5, Issue 2, February 2026.We present a dual‐polarization broadband frequency selective rasorber featuring a transmission window in the middle of its absorption band. The proposed FSR achieves a –10 dB reflection band over 3.68–16.94 GHz with a fractional bandwidth of 128.6%, featuring a minimum insertion loss of 0.3 dB at 10.3 GHz.
