Consider a plane wave in air is normally incident upon a lossless nonmagnetic dielectric medium relative electrical permittivity of 4. The incident H field phasor is given as H=a,Bear, (A/m). Determine; a) Electric field phasor, b) Average incident power density vector c) Average reflected power density vector d) Average power density in the dielectric medium. e) Total power incident on the dielectric boundary surface area of radius 60 cm.
