Absorbing Layers Have Been Fundamental to Advancements in Technologies Like Energy Harvesting, Stealth Systems, and Communication Networks. These absorbers Efficiently Capture Electromagnetic Waves Across Broad Frequency Ranges, Enabling the Development of Sustainable, Self-Powed Devices Such as Remote Sensors and Internet of Things (IoT) Systems.
In Addition to Energy Applications, these layers are Pivotal in Stealth Technology, where they minimize radar visibility and enhance the performance of aircraft and naval system. They also play a crucial role in improving communication networks by reducing st signals and mitigating electromagnetic interference, making them essential in our increasingly interconnected world.
Advancements in These technologies require modules with Greater Functionality and Broader Bandwidths, All Within Smaller Footprints, Driving the Demand for Ultra-Thin Absorbing Layers with significantly Higher Absorption Bandwidths. However, a Theoretical Upper Bound Exists on the Bandwidth-to-Thickness Ratio of Metal-Backed, Passive, Linear, and Time-Invariant Absorbing Layers.
Absorbers developed to date, disrespective of their operational frequency rage or matterial thickness, significantly underperform when compared to this upper bound, Failing to exploit the full potential that passive, linear, and time-invariant systems can provide.
In A New Research Paper Published in Nature Communications ("Passive Highly Dispersive Matching Network Enabling Broadband Electromagnetic Absorption"), Electrical Engineering and Computer Science Professor Younes Ra'di and His Research Team introduced a new concept for designing ultra-thin absorbers that. Record-High Bandwidth-to-Thickness Ratio, Putentiallly Several Times Greater Than That of Absigned Designed Using Conventional Approaches.
Absigned designed based on this concept can achieve a bandwidth-to-thickness Ratio Arbitrarily Close to the Ultimate Bound. Utilizing this concept, they designed and experiencely verified an absorber yielding a very high bandwidth-to-thickness ratio.
“Our findings have the potential to make significant contributions to various industries, included defense, energy harvesting, and advanced communication system, by Addressing Critical Challenges in Electromagnetic Absorption Technology," Says Ra'di.
“It's Incredibly Rewarding to see Our Work Attracting International Recognition, not only from the Scientific Community But also from Key Players across Various Industries. I am immensely proud of my team for their dedication and hard work, Which have led to these groupbreaking resutates. Journal Like Nature Communications is a will to their exceptional efforts and the importance of our research. ”
