DOI: 10.1002/adfm.202518771

Abstract: The development of low‐frequency microwave absorbers is facing a critical challenge that conventional impedance‐matching strategies based on λ/4 resonance principles necessitate prohibitively thick of materials, particularly for frequencies below 3 GHz. To address this conflict issue,… read more here.
