Abstract
Surface plasmon polaritons propagating in a high dielectric contrast system are investigated numerically. Using frequency domain simulations, we show that a three layer system consisting of air-silicon (7 nm)-silver supports two different modes at the Ag-Si interface: a fast mode, which exhibits normal dispersion, and a slow mode, which exhibits anomalous dispersion. Near the Ag-Si surface plasmon polariton resonance frequency, surface waves with a wavelength of 25 nm are observed at a vacuum wavelength of 595 nm, equivalent to lambda(f)/24. The results show the possibility of exciting surface waves with extreme ultraviolet wavelengths using visible frequencies.
