Floquet-Bloch Theory for Dispersive Time-varying Metasurfaces
Mohammad Mojtaba Sadafi, Sandeep Inampudi, Hossein Mosallaei
Light-matter interaction in time-varying metasurfaces brings about phenomena that transcend the limits of static systems. Temporal modulation enables energy exchange between light…

Diffractive optics approach towards subwavelength pixels
Bo Fan, Sandeep Inampudi, Viktor A. Podolskiy
Pixel size in cameras and other refractive imaging devices is typically limited by the free-space diffraction. However, a vast majority of semiconductor-based detectors are based o…

Interscale Mixing Microscopy: far field imaging beyond the diffraction limit
Christopher M. Roberts, Nicolas Olivier, William P. Wardley +4
We present an analytical description and an experimental realization of interscale mixing microscopy, a diffraction-based imaging technique that is capable of detecting wavelength/…
