A uniform plane wave is traveling in the human body. Assume that the x-y plane resides just below the surface of the torso and the wave travels in the +y direction into the body (torso). The constitutive parameters of the body are relative permittivity is 54, relative permeability is 1, and o =1.5 S/m. If the electric field at z = 0 is E(0, t)=10cos (2 x 103t+15) (V/m), a. Obtain expressions for E(z,t) and H(z,t). b. Determine the power density at 5 cm into the human body.

A uniform plane wave is traveling in the human body. Assume that the x-y plane resides just below
the surface of the torso and the wave travels in the +y direction into the body (torso). The
constitutive parameters of the body are relative permittivity is 54, relative permeability is 1, and o
=1.5 S/m. If the electric field at z = 0 is E(0, t)=10cos (2 x 103t+15) (V/m),
a. Obtain expressions for E(z,t) and H(z,t).
b. Determine the power density at 5 cm into the human body.
