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,
New Gallery (London) had been made to show contemporary decorative arts in London since the Grosvenor Gallery's Winter Exhibition of 1881, which included cartoons for mosaic, tapestry, and glass, and the Society's annual (later triennial) exhibitions at the New Gallery were important events in the Arts and Crafts Movement at the end of the 19th century.< In 1890, the New Gallery held an important exhibition of Tudor portraits and relics under the auspices of Queen Victoria. The New Gallery was the setting for a major Burne-Jones retrospective in 1892–93 and a memorial exhibition of his works in 1898. In 1893 the New Gallery
