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,
Konami 80's Arcade Gallery of actual overseas arcade kits have yet to be found. The PlayStation home ports were released in Japan and North America, but not PAL regions. Konami 80's Arcade Gallery While many compilations on home consoles predate "Konami 80's Arcade Gallery", it is one of the earliest examples of an arcade reissue of classic games, being preceded only by the "Namco Classics Collection" series. It is also, to date, one of only two arcade compilations with both a coin-op and consumer release (the other being Space Invaders Anniversary). The collection was developed for the System 573 arcade system - hardware based
