Exploring the role of hyperbolicity in surface enhanced Raman sensing
Mihir Kumar Sahoo, Abhay Anand V S, Nihar Ranjan Sahoo +1
A plasmonic nanostructure-based substrate, serving as a surface-enhanced Raman scattering (SERS) substrate, enhances the Raman scattering of molecules. By employing an electron bea…
Twisted hyperbolic van der Waals crystals for full Stokes mid-infrared polarization detection
Nihar Ranjan Sahoo, S. S. Jatin Prasath, Brijesh Kumar +1
Investigating the polarization properties of light in the mid-infrared (mid-IR) spectrum is crucial for molecular sensing, biomedical diagnostics, and IR imaging system technologie…
Exceptional point sensing via energy loss profile in a non-Hermitian system
Parul Sharma, Brijesh Kumar, Nihar Ranjan Sahoo +1
The heightened sensitivity observed in non-Hermitian systems at exceptional points (EPs) has garnered significant attention. Typical EP sensor implementations rely on precise measu…
Polaritons in photonic hypercrystals of van der Waals materials
Nihar Ranjan Sahoo, Brijesh Kumar, S. S. Jatin Prasath +3
In-plane Hyperbolic Phonon polaritons (HPhPs) are quasiparticles formed via coupling of photons and optical phonons in in-plane hyperbolic materials and offer unique applications i…
