Pinholes Meet Fabry-Pérot: Perfect and Imperfect Transmission of Waves through Small Apertures
Waves, of wavelength λ, transmit poorly through apertures of dimensions ℓ≪λ. Here it is shown that coupling of a subwavelength aperture to an electromagnetic oscillator makes it possible for a focused, diffraction-limited beam that impinges on the aperture to undergo perfect transmission. Ignoring n...
