Summary on Grant Application Form
The aim of this project is to develop an ultra-high sensitivity detection system for near-field dipolar radiation, for example as emitted by proton spin reversal during magnetic resonance imaging. Radiation from a central dipolar source will be synchronously coupled to a magneto-inductive wave propagating in a circular arrangement of coupled L-C loop resonators. Magneto-inductive waves are a new type of slow wave with easily controllable dispersion characteristics. The loop resonators themselves will provide signal amplification through their high Q-factor and coupling. Two techniques will be investigated to increase signals still further: parametric amplification using a second set of non-linear coupled resonators, and the use of cryogenic resonator elements. The application of the detection system to magnetic resonance imaging and spectroscopy and the location of RF signal sources in interventional procedures will be studied.
