Dirkx, D. (author), Prochazka, Ivan (author), Bauer, Sven (author), Visser, P.N.A.M. (author), Noomen, R. (author), Gurvits, L. (author), Vermeersen, L.L.A. (author)At present, tracking data for planetary missions largely consists of radio observables: range-rate (Doppler), range and angular position (VLBI/Δ DOR). Future planetary missions may use Interplanetary Laser Ranging (ILR) as a tracking observable. Two-way ILR will provide range data that are about 2 orders of magnitude more accurate than radio...journal article 2018

Chandra Mouli, G.R. (author), Bauer, P. (author)Charging electric vehicles (EV) from photovoltaic (PV) panels provides a sustainable mode of transportation. In order to reduce the net costs of charging EV from PV and the grid, the PV generation and/or the EV charging can be controlled based on the energy prices in the grid. The traditional approach to designing the solar system for EV...conference paper 2018

Shekhar, A. (author), Soeiro, Thiago B. (author), Qin, Z. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)An important step in Voltage-Source Modular Multilevel Converter (MMC) design is the selection of adequate semiconductor blocking voltage class. This paper highlights that particularly for grid connected medium voltage applications, the choice of suitable switch blocking voltage class is not so straightforward. The market available switch...conference paper 2018

(author), Ebert, H. (author), Bauer, G.E. (author), Gross, R (author), Goennenwein, S. T.B. (author)The observation of the spin Hall effect triggered intense research on pure spin current transport. With the spin Hall effect, the spin Seebeck effect and the spin Peltier effect already observed, our picture of pure spin current transport is almost complete. The only missing piece is the spin Nernst (-Ettingshausen) effect, which so far has...journal article 2017

Sharma, S. (author), Blanter, Y.M. (author), Bauer, G.E. (author)Brillouin light scattering is an established technique to study magnons, the elementary excitations of a magnet. Its efficiency can be enhanced by cavities that concentrate the light intensity. Here, we theoretically study inelastic scattering of photons by a magnetic sphere that supports optical whispering gallery modes in a plane normal to...journal article 2017

Shekhar, A. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)Since shipboard power systems are inherently islanded and consist of energy intensive sources and loads, it is an interesting application for dc microgrids. The object of this paper is to explore the merits of dc based shipboard power distribution as compared to conventional ac solutions. A survey of current initiatives, emerging concepts and...conference paper 2017

(author), Kirilyuk, Andrei (author), Rasing, Theo (author), Saitoh, Eiji (author)To know the properties of a particle or a wave, one should measure how its energy changes with its momentum. The relation between them is called the dispersion relation, which encodes essential information of the kinetics. In a magnet, the wave motion of atomic spins serves as an elementary excitation, called a spin wave, and behaves like a...journal article 2017
