Evanescent waves are stored in the air gap of a dielectric\/metal\/air gap\/metal planar microcavity. For an air gap with a micron scale distance between the two metals, incident light excites the optical interface modes on the two metal-air interfaces simultaneously, being accompanied by enhanced evanescent fields. Numerical simulations show that the reflected light depends remarkably upon distributions of the enhanced electric fields in the air-gap at the optical mode excitations. The metallic microcavities have a Q value on the order of 102, as determined from calculations. Experimentally, a small mechanical variation of the air-gap distance exhibited a change of reflectivity.<\/jats:p>","DOI":"10.3390\/s100908751","type":"journal-article","created":{"date-parts":[[2010,9,27]],"date-time":"2010-09-27T11:23:33Z","timestamp":1285586613000},"page":"8751-8760","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Characteristics of Metal Enhanced Evanescent-Wave Microcavities"],"prefix":"10.3390","volume":"10","author":[{"given":"Takashi","family":"Wakamatsu","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronic System Engineering, Ibaraki National College of Technology, 866 Nakane, Hitachinaka, Ibaraki, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2010,9,21]]},"reference":[{"key":"ref_1","unstructured":"Yariv, A (1971).
