You don't need the scare-quotes, Lizzie, it's a real thing.
They weren't "scare-quotes", nupogodi (and those aren't either) - they were actual quotes! I was quoting you!
Yes, I know. And I am very well aware that total internal reflection, with or without scare quotes, is not found in nature - there is always some loss.
But reflection sure as heck improves transmission, as the Whispering Gallery demonstrates.
Yes, you get loss of amplitude through absorption over distance, but if you are also getting reinforcement from reflection you will hugely increase the power of the signal per unit distance.
As is easily demonstrated! There's a reason buskers like to play in subway tunnels!
