Abstract :
A simple but effective method is proposed to incorporate the effects of a radiofrequency (RF) shield into the analysis of RF resonators for magnetic resonance imaging (MRI) applications. It Is shown that the method can predict the resonant frequencies of RF resonators within 5% of the measured values.
