Ultralow‐Frequency Epsilon‐Near‐Zero States in 3D‐Printed High‐Entropy Alloy Metacomposites for Ultra‐Thin Perfect RF Absorption

Advanced Materials, EarlyView.
Rozanov causality limit—a compulsive proportional thickness‐wavelength relationship (nd ∝ λ)—makes it challenging to develop perfect absorption with both thin thickness and low frequency. Herein, a cocktail effect in high‐entropy alloys (HEA) is crucially utilized for lowering plasma frequency to achieve epsilon‐near‐zero states, which finally enables ...
