Electromagnetic and thermal properties for 300 MHz, 500 MHz and 1 GHz of brain grey matter, brain white matter and blood used in the electromagnetic simulations with the human voxel model “Ella” [28]. All other material parameters used in the electromagnetic field simulations (e.g., skin or fat) can be found in [29]
