Optimized Design of the Shielded-Loop Resonator
Journal of Magnetic Resonance, Series A 1996

The shielded-loop resonator is known to have low capacitive sample loss due to perfect balancing. We present a new analysis of the unbalanced driven shielded-loop resonator that calculates the resonance frequencies and also determines some design considerations. The analysis enables us to optimize the use of this resonator. Theory and design considerations are shown to agree with observations in measurements on two coils, with various sizes and frequencies
