DOI: 10.1109/tim.2023.3249248
Abstract: This manuscript proposes a geometric-programming (GP)-aided approach for reducing the conversion time of digitizers for resistive sensors. The digitizer, comprising a relaxation oscillator circuit, partitions the sensor span into multiple regimes. An optimization problem with… read more here.

DOI: 10.1364/oe.467479
Abstract: We investigate the possibility of frequency conversion in time-varying metasurfaces, composed of graphene microribbon arrays (GMRAs) with time-periodic modulation of their conductivity. We present a quasi-static model for the interaction of light with a temporally… read more here.
