Whispering-gallery wave known as surface plasmons has been demonstrated in the form of whispering-gallery waves, and likewise for exciton-polaritons in semiconductors. Galleries simultaneously containing both acoustic and optical whispering-gallery waves have also been made, exhibiting very strong mode coupling and coherent effects. Hybrid solid-fluid-optical whispering-gallery structures have been observed as well. Whispering-gallery wave Whispering-gallery waves, or whispering-gallery modes, are a type of wave that can travel around a concave surface. Originally discovered for sound waves in the whispering gallery of St Paul’s Cathedral, they can exist for light and for other waves, with important applications in nondestructive testing, lasing, cooling and sensing,
The Whispering Vault for his game, including the "Dangerous Prey sourcebook" (1995) and a three-panel GM screen (1995). Chris Pramas decided to create a company to publish "The Whispering Vault"; in early 1996 he acquired "The Whispering Vault" rights from Mike Nystul and formed Ronin Publishing with his brother, Jason Pramas, and their mutual friend, Neal Darcy. The company's first publication was "The Book of Hunts" (1997), a book of adventures for "The Whispering Vault"; Ronin Publishing had plans for another "Whispering Vault" book called "Mortal Magic" but they were never able to print it, or anything else for the game.
