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,
Mendel Art Gallery the suggestion of the then mayor, S. L. Buckwold. The building was extended in 1975. On September 18, 2006, the gallery suffered smoke and water damage from an early morning fire in the loading dock area. It reopened nine weeks later with increased focus on national and international art. In 2009, the Board of Trustees of the Mendel Art Gallery decided to replace the building, which had come to be too small and needed expensive upgrades, with a larger facility on a different site. A new gallery, associated with the Remai Arts Centre, is to be opened at River Landing,
