Extraordinary optical diffraction

Extraordinary optical transmission (EOT) is the phenomenon of greatly enhanced transmission of light through a subwavelength aperture in an otherwise opaque metallic film which has been patterned with a regularly repeating periodic structure. Generally when light of a certain wavelength falls on a subwavelength aperture, it is diffracted isotropically in all directions evenly, wit… Webseparation due to diffraction, then diffraction limits the imagequality. The “f-number”of a lens is defined as f/D. To minimize diffraction, you want a small f-number, i.e., a large aperture*. d Photosensor: 7 mm 5 mm Pixel *This assumes a ‘perfect lens’. In practice, lens aberrations limit the resolution if D is toobig. Photosensor ...
