Planar Coils for NMR Microspectroscopy
Planar microcoils suffer from a reduced sensitivity compared to solenoidal microcoils. However, because of their planar geometry, they can be more easily fabricated and integrated into microanalysis systems through the use of microfabrication techniques. This thesis investigates the feasibility of …

Design of a superconducting Bias-Tee
… a quartz process. We also report the design of planar coils, which have a quality factor of 2400 for the silicon process and 2000 for the quartz process.

Thermal Hydraulic numerical analysis of Fusion superconducting magnet systems
… pre-existing 4C code, was modeled for various coils with or without external cooling circuit as required. Henceforth, it was implemented against the wide range of transients, fast transients (~ few seconds) as well as slow transients (~ few days or weeks) to test the flexibility of the code in …

Entwicklung und Charakterisierung von mikrostrukturierten Planarspulen für Kernspinresonanz-Anwendungen
… low field devices, commonly based on solenoid coils of conventional copper wire, have already been developed to analyse centimetre-sized objects. However, the demand for a portable device, which enables a millimetre-sized structure analysis, was not fulfilled, especially to image small …

Synergetic Attenuation of Stray Magnetic Field in Inductive Power Transfer
… stray magnetic field exists around the coils when charging the electric vehicles (EVs) with inductive power transfer (IPT), owning to the large air gap between the transmitter and receiver. The methods for field attenuation usually introduce extra losses and reduce the efficiency. This …
