Kate:
I realize that this is a bit of a drift from my original request about
mannequins and absorption simulation. One of our engineers here said that he
had read that the most affected body component (heating effects at around 900
MHz) is cerebo-spinal fluid.
Is this true, or do you have more heating effect (from a typical cell
phone type emitter) on ear lobes and/or scalp?
