WebSep 21, 2010 · This article presents the concept of storing optical energy using a metallic air gap microcavity. 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 … WebPathological Q-waves are evidence of myocardial infarction Myocardial infarction – particularly if extensive in size – typically manifests with …
