WebWhen a wave undergoes a change in refractive index, some the wave is reflected and some of the wave (may be) refracted. No phase change for the 'refracted' wave. But the … Web23. aug 2013 · We report an easy-to-build, compact, and low-cost optical fiber refractive index sensor. It consists of a single fiber loop whose transmission spectra exhibit a series of notches produced by the resonant coupling between the fundamental mode and the cladding modes in a uniformly bent fiber. The wavelength of the notches, distributed in a …
Web21. nov 2024 · There's no a priori reason to expect any phase relationship between the incident and reflected (or transmitted) waves, as they are different beams in different places moving in different directions and their phases are ultimately subject to the choice of convention. But there's no discontinuity anywhere. – Emilio Pisanty Nov 22, 2024 at 17:28 Web29. júl 2011 · This multitude of wave vectors makes it non-trivial to define a single refractive index.
