T5
For a homogeneous dielectric medium with the refractive index of n(w), the
corresponding Maxwell's equations in the frequency domain are given by
V x E = jwµ,H; V × H = -jwn’ɛ,E; V · E = 0; V · H = 0
If k is the wavevector of a plane wave solution at the frequency w, please determine (a)
|k| in terms of w, (b) the phase velocity vpand the group velocity vg at the frequency w for
the waves propagated in the medium, (c) the first derivative of the group velocity vg with
d(v7')
respect to the wavelength 1 is often used as a parameter for the dispersion, D =
da
Please determine the relation between this D parameter and the B2 dispersion parameter.
Q: An AM radio signal propagating in free space has:
E = Eo sin(1200πt - βz)ax
H= (Eo / η)*sin(1200πt- βz)az
Express these in phasor form and detrmine β and η such that the fields Satisfy Maxwell’s equations.
