Journal ArticleDOI
Active Control of Electromagnetically Induced Transparency Analog in Terahertz MEMS Metamaterial
Prakash Pitchappa,Prakash Pitchappa,Manukumara Manjappa,Chong Pei Ho,Chong Pei Ho,Chong Pei Ho,Ranjan Singh,Navab Singh,Chengkuo Lee +8 more
TL;DR: In this article, a reconfigurable metamaterial with independently controlled bright and dark mode resonators is proposed for advanced manipulation of the classical analog of EIT and slow light effects in the THz spectral region.
Journal ArticleDOI
Sensing with toroidal metamaterial
TL;DR: In this article, a two-dimensional terahertz metamaterial was demonstrated with toroidal resonance in which a pair of mirrored asymmetric Fano resonators possesses anti-aligned magnetic moments at an electromagnetic resonance that gives rise to a toroidal dipole.
Journal ArticleDOI
Reconfigurable MEMS Fano metasurfaces with multiple-input-output states for logic operations at terahertz frequencies.
Manukumara Manjappa,Prakash Pitchappa,Navab Singh,Nan Wang,Nikolay I. Zheludev,Chengkuo Lee,Ranjan Singh +6 more
TL;DR: Examination and active tuning of sharp Fano resonances in a MEMS reconfigurable metasurface possessing multiple-input-output states that performs logic operations with two independently controlled electrical inputs and an optical readout at terahertz frequencies is demonstrated.
Journal ArticleDOI
Active Photoswitching of Sharp Fano Resonances in THz Metadevices.
TL;DR: An active photoswitching of Fano resonances in a terahertz metadevice at low optical pump powers is demonstrated, which signifies the extreme sensitivity of the high-quality-factor resonant electric field to the external light illumination.
