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 The Whispering Vault The Whispering Vault is a horror-themed role-playing game originally published in 1993. At Gen Con 26 Mike Nystul self-published a limited edition of a new horror RPG called "The Whispering Vault" (1993); by the next year, he was ready to release an expanded and more professional version into distribution and thus Pariah Press was born.
