Specific absorption rate as a function of frequency !, parameterized by field strength H0. Thick lines correspond to linear polarized cases, while dashed ones to circular polarized cases. Auxiliary thin line is drawn to explore behavior around resonance ! = 1. Maximum reached for each circular polarized case when condition ! > !L is fulfilled.
