Tangentially, a conceptually similar and equally counterintuitive phenomenon is attenuated total reflection. (https://en.wikipedia.org/wiki/Attenuated_total_reflectance https://en.wikipedia.org/wiki/Attenuated_total_reflectance)
- ncmncm 6y agoFascinating. I had only just learned about "evanescent wave" interactions. The idea is that, alongside wave propagation, E-M mechanics admits numerous non-wave, and therefore short-range solutions. These solutions are necessary to explain total internal reflection. E-M interactions with materials a short distance beyond the boundary can change the reflectance. ATR is clever in using multiple such interactions to sample properties of a material close enough to the boundary.
