Phonon-polariton mediated dual electromagnetically induced transparency-like response in a THz metamaterial
Amit Haldar, Kshitij V Goyal, Ruturaj V Puranik +9
Light and matter can intertwine to create entirely new quantum states in the so-called strong-coupling regime, allowing unprecedented control over electromagnetic waves. In this wo…

Polarization independent lattice-coupled terahertz toroidal excitations
Angana Bhattacharya, Bhagwat S. Chouhan, Bhairov K. Bhowmik +2
The toroidal dipole excitation is an important field for metamaterial research because of their low-loss attribute. In this study, we demonstrate numerically and experimentally, a…
