Unveiling nonlinearities of electromagnetically induced transparency in a THz metamaterial
Amit Haldar, Shriganesh Prabhu, Shovon Pal
Electromagnetically induced transparency (EIT) in terahertz (THz) metamaterials relies on the coherent coupling between a radiative (bright) mode and a subradiant (dark) mode. Unde…

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…

Sensing with Broken Symmetry: Revisiting Bound States in the Continuum
Brijesh Kumar, Elizaveta Tsiplakova, Samuel John +6
Metasurface with bound states in the continuum (BICs) offer exceptional potential for optical sensing due to their inherently high quality (Q) factors. However, the detection of sy…
