[摘要]:We report surface-plasmon-polariton-induced suppressed transmission through two-dimensional arrays of isolated metal disks with a thickness comparable to optical skin depth of the metal. A transmittance dip of -17.5 dB is achieved at the resonant wavelength of 1524 nm, compared to -12 dB for closed film. Coupling the light into the surface-plasmon polariton results in enhanced absorption, which is potentially interesting in solar cell applications. (C) 2010 Optical Society of America |
