Abstract: | The sharp gradient in the intensity of a surface wave over a simiconductor-vacuum interface gives rise to a strong ponderomotive force on electrons and thus generates a second harmonic wave. The power of the second harmonic shows a resonance at (ω and ωp being the wave and plasma frequencies) and tends to a saturation value at very high values of ωp. |
