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 time-average 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. RG-58 is the coax cable that you have been using most frequently in your labs. It has the same geometrical dimensions as the RG-59 cable, but instead of having a dielectric filling with =...
