Synopsis

Keywords: RF Arrays & Systems, Simulations, RF Pulse Design and Fields, parallel transmit coilsWe present a full closed form solution focusing on S-parameters to achieve tuning and matching of the coils by extending the circuit co-simulation (CCS) by enabling introduction of arbitrary matching networks into the CCS without requiring full RF simulation of the network. We validate the method against CCS and demonstrate its applicability to evaluate full-field solutions for 5 different coil model using MARIE.
