Radiofrequency heating of nanoclusters and nanoparticles for enzyme activation
Radiofrequency (RF) fields heat magnetic nanoparticles. Applications include remote drug delivery and noninvasive cancer therapy. The underlying objective is to increase temperatures precisely where desired without heating the surroundings. Before our work, the replicable limit of this precision …

Study of the effects of roughness, ultraviolet radiation, multipactoring and magnetic field on vacuum breakdown
… fusion projects, one of the methods of heating the plasma is through ion cyclotron radiofrequency heating. ICRF antennas are used to this end, while the voltage and hence the power possible to deliver through these antennas is limited because of breakdowns. The focus of this research has …

Design of an ICRF fast matching system on Alcator C-Mod
In Ion Cyclotron Radiofrequency Heating (ICRH) for tokamaks, fast variations of the antenna loading impedance limit flexible and robust high-power operations. In this thesis, novel solutions for real-time matching and reduction of these variations are investigated and studied for implementation on …
