Figure 1.11 Specific absorption rate distribution inside a brain sphere under plane-wave
exposure: The three columns represent values for the xy, yz, and zx planes, respectively. The
corresponding line distributions along (red) the direction and transverse to the direction (blue) of
propagation are shown at the bottom (diameter = 18 cm and frequency = 400 MHz). The direction
of wave propagation is along the x axis.
