+ 8. (10 points) Air-muscle interface. Consider a planar interface between air and muscle tissue. If a plane wave is normally incident at this boundary, find the percentage of incident power absorbed by the muscle tissue at (a) 100 MHz, (b) 915 MHz, and (c) 2.45 GHz. (Hint: The reflection coefficient at the air-muscle interface will be a complex number for lossy materials. T = n muscle - Mair -; I muscle must be a complex n muscle + nair number if the conductivity is not zero (lossy material).) Relative permittivity and conductivity for muscle tissues f (MHz) Relative permittivity er Conductivity o 100 71.7 0.889 51 1.60 2,450 47 2.21 915
