ECGR 3122: Electromagnetic Waves Summer 2022 Homework #4 6/06/22 Name:--- Two optical fibers are connected through a connector as shown in the Figure. In the optical fibers, the attenuation is indicated in dB/km. Fiber (1) is rated as 1 dB/km (a good fiber) the second as 10 dB/km. The source of light is in free space (not shown), at a wavelength of 400 nm (a red laser or light emitting diode). Assume both fibers are low-loss dielectric (which in practice they are: conductivity of glass of 10-¹2 S/m and that propagation is from fiber (1) into fiber (2). Calculate: The exact complex reflection and transmission coefficients at the interface. Fiber (1) Fiber (2) H1 = 1₂ = thi kho €₂ = 4€ a₂ = 10 dB/km Interface &₁ = 66 a₁=1 dB/km Figure
