Sensing with THz metamaterial absorbers
Longqing Cong, Ranjan Singh
Metamaterial perfect absorbers from microwaves to optical part of the electromagnetic spectrum has been intensely studied for its ability to absorb electromagnetic radiation. Perfe…
Ultrafast Switching in Terahertz Metamaterials using Ion Implanted Silicon on Sapphire
Dibakar Roy Chowdhury, Ranjan Singh, Antoinette J. Taylor +1
We demonstrate ultrafast resonance switching of terahertz metamaterials through optical excitation of radiation damaged silicon placed in the gap of single split gap ring resonator…
Ultrasensitive THz sensing with high-Q Fano resonances in metasurfaces
Ranjan Singh, Wei Cao, Ibraheem Al-Naib +3
High quality factor resonances are extremely promising for designing ultra-sensitive refractive index label-free sensors since it allows intense interaction between electromagnetic…
