10.9. Air-glass interface. The magnetic field intensity vector of a TEM wave propagating in air for x>0 is given by Hi=52sin(ωt+10πX)z^ A/m(x in m). The wave is incident at x=0 on the planar interface of a glass medium with relative permittivity εr=4(μr=1) and negligible losses, occupying the x<0 half-space. Compute (a) the frequency of the wave, (b) the wavelength in the second (glass) medium, (c) the instantaneous and complex total electric field intensity vector in the first medium (air), (d) the maxima and minima of the total rms magnetic field intensity in air and glass, respectively, (e) the time-average Poynting vector for −∞<x<∞, and (f) the wave impedance in a plane defined by x=10 cm.
