Plasmonic metasurfaces are investigated that consist of a sub‐wavelength line pattern in an ultrathin (∼10 nm) silver film, designed for extraordinary suppressed transmission (EOST) in the visible spectral range. Measurements with a near‐field scanning optical microscope (NSOM) demonstrate that far‐field irradiation resonantly excites antenna‐like (bright) modes that are localized on the metal ridges. The re‐radiation of these modes into the far‐field interferes destructively with the transmitted wave, thus suppressing transmission almost completely. In contrast, a second type of mode, bound (dark) surface plasmon polaritons (SPPs) launched from an NSOM tip, propagates well across the metasurface, preferentially perpendicular to the grating lines.
