Microwave-stimulated Raman adiabatic passage in a Bose-Einstein condensate on an atom chip
, 2015 We report the achievement of stimulated Raman adiabatic passage (STIRAP) in the microwave frequency range between internal states of a Bose-Einstein condensate (BEC) magnetically trapped in the vicinity of an atom chip.

Photoferroelectric solar to electrical conversion
, 2013 We propose a charge pump which converts solar energy into DC electricity. It is based on cyclic changes in the spontaneous electric polarization of a photoferroelectric material, which allows a transfer of charge from a low to a high voltage. To estimate

Modular Platform for Efficient Wireless Power Transfer to Low-Power Devices
Proceedings of the 4th URSI Atlantic RadioScience Conference – AT-RASC 2024To tackle the economic and ecological challenges introduced by batteries, and avoid their massive deployment in low-power IoT devices, a modular platform is developed to transfer power wirelessly to these devices. The modules in the proposed system are based on a phase-locked loop (PLL) frequency synthesizer and are judiciously controlled by an on ...

Maximizing DC-to-Load Efficiency for Inductive Power Transfer
IEEE Transactions on Power Electronics, 2013 Inductive power transfer (IPT) systems for transmitting tens to hundreds of watts have been reported for almost a decade. Most of the work has concentrated on the optimization of the link efficiency and has not taken into account the efficiency of the driver. Class-E amplifiers have been identified as ideal drivers for IPT applications, but their power
