(author)In this paper, two important dielectric properties, the relative permittivity and the loss tangent of a new commercially available UV-curable SLA resin sample are determined. The characterization of the dielectric material is performed in the millimetre-wave range using an open-cavity Fabry-Perot resonator. According to the manufacturer’s data ´...conference paper 2022

Harvey-Collard, P. (author), Dijkema, J. (author), Zheng, G. (author), Sammak, A. (author), Scappucci, G. (author), Vandersypen, L.M.K. (author)We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a superconducting resonator, achieving spin-photon couplings up to around gs/2π = 40 MHz. As the two spins are brought into resonance with each other, but detuned from the...article 2022

de Gijsel, S.L. (author), Vijn, A.R.P.J. (author), Tan, R.G. (author)This paper proposes an algorithm to localize a magnetic dipole using a limited number of noisy measurements from magnetic field sensors. The algorithm is based on the theory of compressed sensing, and exploits the sparseness of the magnetic dipole in space. Beforehand, a basis consisting of magnetic dipole fields belonging to individual dipoles...article 2022

Nuñez, J. (author), Boersma, A. (author), Grand, J. (author), Mintova, S. (author), Sciacca, B. (author)Infrared absorption spectroscopy is a powerful analytical tool that enables the identification of molecular species. The sensitivity of this technique, that is strongly limited by the small absorption cross-section of molecular vibration, can be greatly improved by resonant interaction with nano-antennas via the surface-enhanced infrared...article 2021

(author)A new method for fast, high resolution interrogation of an array of photonic sensors is proposed. The technique is based on the integrated Fourier transform (FT) interrogator previously introduced by the authors. Compared to other interferometric interrogators, the FT-interrogator is very compact and has an unprecedented tolerance to variations...article 2021

Nicasy, R. (author), Huinink, H.P. (author), Erich, S.J.F. (author), Adan, O.C.G. (author)An improved High-Speed NMR profiling method is introduced that enables to measure capillary action in thin, non-transparent porous media. Liquid profiles can be measured as fast as 10 ms with a spatial resolution of 14.5 µm. Capillary absorption of microliter-sized droplets into non-transparent nylon-6,6 porous membranes was studied. In nylon-6...article 2021

Neural representations of haptic object size in the human brain revealed by multivoxel fMRI patternsPerini, F. (author), Powell, T. (author), Watt, S.J. (author), Downing, P.E. (author)The brain must interpret sensory input from diverse receptor systems to estimate object properties. Much has been learned about the brain mechanisms behind these processes in vision, but our understanding of haptic perception remains less clear. Here we examined haptic judgments of object size, which require integrating multiple cutaneous and...article 2020

Tajdari, F. (author), Berkhoff, A.P. (author), de Boer, A. (author)This paper focuses on extensive numerical and experimental investigations of a thin sandwich acoustic source. Due to an energy inefficient actuation design, a thin sandwich acoustic source that was proposed in an early study is redesigned and reconstructed in the current research. The thin acoustic source in the present paper is actuated by long...article 2020

(author)Silicon spin qubits are one of the leading platforms for quantum computation1,2. As with any qubit implementation, a crucial requirement is the ability to measure individual quantum states rapidly and with high fidelity. Since the signal from a single electron spin is minute, the different spin states are converted to different charge states3,4....article 2019

Commonly, the NTM location is determined using electron cyclotron emission (ECE) and this is used to apply electron cyclotron heating (ECH) on the NTM location. In this paper, an inline ECE...article 2019
