For the previous problem, repeat the calculations of SAR assuming a six-layered spherical model of the human skull (similar to that of Figure 2.25) of outer radius a = 10 cm. Plot Pa/Pi vs. frequency for 0.1 < f="">< 3="" ghz=""> Pa = absorbed power, Pi = incident power, _ = 2_a/_, _ is the wavelength in the external medium. Use the dimensions and electrical properties shown below.
