The forearm complex permittivity analysis, the impedance, and the effects of tissue property variance on the impedance. a the complex permittivity for skin, fat, and muscle, b layer-by-layer impedance (left) and the total impedance (right) with the skin thickness 1.5 mm and the fat of 2.5 mm (muscle, musch thicker than the skin and fat was considered as virtual infinite layer), c the total impedance changes due to skin (top raw) and fat (bottom raw) thicknesses from 1 to 3 mm, d the total impedance changes due to skin, fat and muscle permittivities from -20 to 20% variable
