We performed 3-D electromagnetic simulations of coaxial leads and numerically obtained the lead models to evaluate power deposition and the voltage induced at the lead proximal end with the lead models. No correlation between peak volume loss density and deposited powers at the tip and the ring was observed. In some cases deposited power at the ring exceeded deposited power at the tip. However further extensive simulations of induced heating behavior should be done before final conclusions regarding coax lead design preferences are made.
