Radiation power loss, or the radiated power of a coil that is not absorbed into the sample, is assumed to be a problem at high field in MRI, as it is known to increase with the frequency (ω) and coil-bounding area (A): RLOSS α A2 * ω4 [1,2]. Various authors suggest that the effects of radiation loss, such as decreased SNR and coil Q, can be mitigated by adding RF shielding to coils used at high field.
