 Abstract: We built four prototypes of high resolution surface-based human head models that can be simulated in a reasonable time by a commercially available frequency domain solver-ANSYS HFSS-and evaluated the influence of cerebrospinal fluid and of the upper part of the human torso on field propagation estimates of traveling wave excitation at 297.2 MHz. Combining neighboring triangular faces located in the same plane into a single one is an approach that achieves simulations of high-resolution human models previously not accessible to tetrahedral-mesh-based solvers. If electrical contact between anatomically connected parts of CSF is correctly considered, CSF was found to partially shield brain tissues from the incident RF field.
