In this work a simple, efficient method to designing a transmission line volume resonator coil for MR applications is presented. A multiconductor transmission line is represented as a multiport network using its port admittance matrix. Closed form solutions for port resonant mode frequencies are calculated by solving the eigenfunctions of the port admittance matrix using block matrix and circulant block matrix algebra. Detailed analysis and simulated results are presented and compared with standard published results. A dual-tuned surface coil is developed to demonstrate the efficacy of the proposed method.
