Enhanced Microwave Trapping and Loss Capabilities of TiN/RGO/PDMS Metacomposites across a Wide Range of Temperatures.

ABSTRACT: According to the relationship between unit size and wavelength, electromagnetic waves (EMWs) in metacomposites can be effectively absorbed through inherent loss mechanisms. However, limited loss ability has emerged as a primary obstacle to achieving efficient EMW absorption (EMWA) performance. The challenge of enhancing the attenuation of corresponding metacomposites remains important. In this study, we prepared elaborate titanium nitride/reduced graphene oxide units with controllable conductivities and sizes, which formed the microwave antireflective surface of metacomposites. This configuration contributes to improved impedance matching and reduced temperature sensitivity concerning EMWA performance. More importantly, EMWs experience repeated collisions and loss, along with multiple refl
