IEEE Day Special Talk: Tunable Terahertz Absorbers

Terahertz (THz) waves, lying between microwaves and infrared in the electromagnetic spectrum, hold enormous promise for applications in high-speed communication, non-invasive imaging, security screening, and advanced sensing. A critical component for harnessing this potential is the development of tunable THz absorbers—engineered structures and materials capable of dynamically controlling the absorption of THz radiation. Leveraging technologies such as metamaterials, graphene, phase-change media, and liquid crystals, these absorbers enable real-time reconfigurability in response to electrical, optical, thermal, or mechanical stimuli. Such tunability paves the way for adaptive THz systems, offering breakthroughs in stealth technology, environmental monitoring, medical diagnostics, and energy harvesting. Ongoing research focuses on achieving broadband performance, low loss, and seamless integration into compact devices.

Agenda

Terahertz (THz) waves are emerging as a key enabler for high-speed communication, imaging, and sensing. Tunable THz absorbers—based on metamaterials, graphene, and smart materials—allow dynamic control of absorption using electrical, optical, or thermal stimuli. Their reconfigurability opens pathways for adaptive devices in security, healthcare, and energy applications, making them a vital frontier in next-generation technologies.
