A plane wave field E = 10 cos( ωt βz )ˆ x V m is propagating in vacuum in + z direction and is incident on z = 0 plane which happens to be the boundary of a perfect dielectric having permittivity 4 o and permeability μ o in the region z > . Calculate: a) The reflected and transmitted electric fields in terms of reflection and transmission coefficients Γ = η 2 η 1 η 2 + η 1 and τ = 1 + Γ for the described interface. Express the fields in phasor form. b) The incident, reflected, and transmitted H fields in A/m units. Express the fields in phasor form. c) The timeaverage power per unit area transported by the incident, reflected, and transmitted waves in W/m 2 units. Are the calculations compatible with energy conservation principle? Explain. 2. RG58 is the coax cable that you have been using most frequently in your labs. It has the same geometrical dimensions as the RG59 cable, but instead of having a dielectric filling with =...
