WebQuestion: For radio and microwaves, the depth of penetration into the human bod1/is proportional to lambda 1/2. If 31 MHz radio waves penetrate to a depth of 14 cm. how far do 2.3 GHz microwaves penetrate? Express your answer to two significant figures and Include the appropriate units. Show transcribed image text Expert Answer WebThe penetration depth is used to denote the depth at which the power density has decreased to 37 % of its initial value at the surface. Materials with higher loss factor ε r ’’ (imaginary part of the complex permittivity) show faster microwave energy absorption. The power density will decrease exponentially from the surface to the core region.
