The Nonreciprocal Mie-surfaces
Dheeraj Pratap
Hemispherical amorphous silicon nanoparticles exhibit asymmetric optical scattering for forward illumination (base-to-apex) and backward illumination (apex-to-base). There exists a…

On the nonreciprocal propagation of light waves in asymmetric lossy system of thin films
Dheeraj Pratap
Optical nonreciprocity is the phenomenon where light behaves differently when traveling in the forward direction compared to the backward direction. This nonreciprocal behavior is…

Perfect absorption of molecular vibration enabled by critical coupling in molecular metamaterial
Govind Dayal, Dheeraj Pratap
The absorption and emission spectrum arising from the vibrational motion of a molecule is mostly in the infrared region. These fingerprint absorptions of polar bonds enable us to a…
