Which is false for an electromagnetic wave perpendicular to the plane surface separating the two dielectric mediums? The transmission coefficient may be less than 0. The transmission coefficient can be greater than 0. The reflection coefficient can be greater than 0. The reflection coefficient may be less than 0.
A plane wave is normally incident from medium 1 ( 81, 41, Š1 ) to medium 2 (82, H2, Š2). Write down the expression for the E- field reflection and transmission coefficients. Calculate the amplitude reflection coefficient from air (µ = µ0 = 4x 10" H/m , &a = 8.85 x 10 -12 F/m) to glass ( u = 40 = 47 10-7 H/m , ɛg = 1.99 x 10 -11 F/m ). For a 1 mW laser power normally incident from air onto a glass surface , calculate how much power would be transmitted into the glass? (assume that the material parameters at the laser frequency are the values given here). If a quarter wave layer is applied onto the glass surface, what should be the value of its č and e in order to reduce the reflection coefficient to zero?
A uniform plane wave propagating in a medium has E=2e"sin(10°t-ßz)ŷ V/m. If the medium is characterized by ɛR=1, PR=20, and o=3 S/m, find a, B and H.
