Light trapping by arbitrarily thin cavities
Simple plasmonic multilayers are found to perfectly trap electromagnetic waves around specific incidence directions, regardless of the sample thickness. Such a counterintuitive feature is acquired via increasing unboundedly the effective path length of the ray into the film with proper tilt of the o...
