摘要: We present a theoretical study of ultrafast light propagation through periodic array nanoapertures in an optically thick metal film. Studying the 10-fs pulses shorter than damping time surface plasmon excitations at interfaces film, we find pronounced temporal oscillations transmitted light. The reflect coupling polaritons both via photon tunneling nanohole channel. diameter nanoholes is main parameter governing period and these oscillations. Radiation scattering identified as important mechanism. Our results give insight into physics transmission gratings clear guidelines for designing optical properties nanostructures.
