Hogenhout, Kees (author)The final goal of this thesis is to figure out if it is possible to design an eight-band LTE antenna for <$0,20 with the same performance, quality and tunability as the current available eight-band LTE antennas. In the introduction the state of the art is presented where the most common currently available comparableantennas and modules are...master thesis 2019

Degasperi, Andrea (author)Photoconductive antennas (PCAs) have been extensively utilized for the generation of broadband pulses over very large bandwidths. PCAs rely on a semiconductor (e.g. LT- GaAs) gap pumped by a laser and coupled to a passive structure biased at a certain voltage level. When the laser impinges on the semiconductor gap with an appropriate carrier...master thesis 2019

van den Bogert, Bart (author)Due to technology trends such as autonomous driving, the need for robust safety in the automotive industry increases. The safety comes from sensors that are able to image the environment and systems that use this information to avoid incidents and retain maximum safety. Detection of pedestrian has high importance since a missed detection can be...master thesis 2018

van der Enden, Kian (author)Majorana zero modes have been proposed as building blocks of intrinsically fault-tolerant quantum computers. Currently, externally applied magnetic fields are necessary to induce Majorana zero modes in carefully engineered systems. Topological qubit state readout is realized by parity sensing of Majorana islands. However, fast and high fidelity...master thesis 2017

van Velden, Karel (author)Airfoil optimizations require costly high-fidelity solvers. By replacing the expensive solver with a cheap to evaluate surrogate model genetic optimization becomes feasible and a global optimum can be obtained. This thesis investigates applicability of surrogate model based optimization for airfoil optimization and provides recommendations...master thesis 2017
