Find the intensity of reflected and transmitted waves through an interface between two linear non-conducting media in terms of the intensity of the incident wave and the indices of refraction of the two media. Note: To do this, suppose a plane wave of frequency ω and electric field polarization in the x direction is traveling in the positive z direction. The wave approaches the interface between two media on the xy plane from left. Write complex waves equations for the...
i) Sketch a ray diagram of a normally polarized electromagnetic field interacting with a glass/air interface. Calculate the critical angle for the glass/air interface (nI(pure glass).5; n2(air)-l). For this calculation, you can ignore the polarization because the critical angle is the same for either normal or parallel normalisation. ii)Derive an expression for the wavelength of the transmitted wave as a function of the refractive index ni at®i-0c from the phase matching boundary requirement at the glass/air interface (see Fig. 1)....
