WebSep 5, 2012 · Optically thin metal gratings of high filling factor can support surface plasmon polariton modes at their horizontal metal boundaries and vertical cavity modes inside their slits. These modes are coupled through the metal stripes and the slits. WebSep 16, 2024 · The experiment setup is composed of two parts: (i) the optical-field-manipulating system and (ii) the scattering imaging system. The optical-field-manipulating system consists of the 4 f system, a spatial light modulator (SLM), two Fourier lenses (L3 and L4), a spatial filter (F), two λ/4 wave plates, and a Ronchi grating (G).
