Transmission line
resonators are often used as coils in high field MRI. Due to distributed nature
of such resonators, coils based on them produce inhomogeneous field. This work
investigates application of series capacitors to improve field homogeneity
along the resonator. The equations for optimal values of evenly distributed
capacitors are presented. The performances of the segmented resonator and a
regular transmission line resonator are compared.
