Special Issue Information

Dear Colleagues,

High-performance material research has facilitated the replacement of bulky, expensive, and poorly integrable traditional absorbers with compact integrated devices. Electromagnetic absorption over the microwave and terahertz regime has drawn increasing attention in many applications as in electromagnetic compatibility, radar cross-section reduction, energy harvesting, design of selective thermal emitters and biosensors, etc. Moreover, the advancement of military stealth technology results in large demand of microwave absorbing materials. High-performance materials, such as magnetic materials, carbon-based materials, flexible/stretchable materials, biomaterials, tunable materials, and metamaterials can be used to design near-perfect absorbers with subwavelength thickness and broadband absorption. Furthermore, the introduction of graphene into electromagnetic absorbers opens new challenges in absorber design and applications. Graphene is a suitable alternative for expensive metals used in modern absorbers, such as gold and silver, thanks to its reconfigurability and its higher wave absorption rate. Another approach for maximizing absorption is the combination of graphene and metallic metamaterials.

This Special Issue aims to present cutting-edge progress in the application of high-performance materials for microwave and terahertz absorption. The scope covers all aspects of theoretical and experimental research towards the development of highly efficient electromagnetic wave absorbing materials and devices.

It is our pleasure to invite you to submit review articles, regular research papers and short communications for this Special Issue: "Applications of High-Performance Materials for Microwave and Terahertz Absorption".

The challenge of developing a high-efficiency microwave absorbent remains, because of the compatibility between microwave absorption and high-temperature-resistant performance in practical application. Herein, a facile method is used to obtain serial MXene/BN-zxy composites, where zx:y indicates the weight ratio of MXene and boron nitride (BN) in the composites, with adjustable microwave absorption performance (MAP) which can be regulated by the ratio of MXene and the BN nanosheet. In particular, the as-prepared absorbents with supercapacitance-like structure significantly enhanced the MAP and could be served more than 900 °C. The results of MAP reveal that the minimum reflection loss (RL) can reach −20.94 dB with a MXene/BN-101 composite coating thickness of 4.0 mm; the effective attenuation bandwidth (RL< −10 dB, i.e., 90% microwave energy is attenuated) is up to 9.71 GHz (7.94–17.65 GHz). From a detailed analysis, it is observed that attenuation is the critical limiting factor for MAPs rather than impedance mismatch, which can be assigned to the poor MAP of BN nanosheets. In any case, as-prepared absorbents have potential applications in the field of heating components. Full article
