Abstract:
1. An electromagnetic resonance device, comprising: an input reflector substantially reflective to a first radiation having a wavelength of interest; an output reflector in a plane substantially parallel to the input reflector and not completely reflective to a second radiation having the wavelength of interest; a reflective aperture layer disposed on the output reflector and including an aperture; and a periodic dielectric medium disposed between the input reflector and the output reflector, the periodic dielectric medium configured with a negative refraction at the wavelength of interest, wherein radiation having the wavelength of interest enters the resonance device through the input reflector, is reflected back and forth between the input reflector and the output reflector, and after each reflection is focused and refocused by the periodic dielectric medium on the input and output reflectors to intensify the radiation that is output as emitting radiation through the aperture.
