摘要:
運用角譜表示的矢量衍射理論,以平面波微小圓孔的非傍軸衍射為例,給出了垂直於光束傳輸方向的橫截面上不同定義的三種光強(傳統光強I、功率密度Jz、時間平均能流密度矢量的z分量〈Sz〉)的計算公式,並進行了詳細的數值計算和比較研究.指出對微小孔衍射的能量傳輸,必須考慮光場的矢量特性.套用能流密度矢量S和功率流密度矢量J,分別計算了微小孔非傍軸衍射的透射係數,得到了一些新的結論.

Light Intensity of Nonparaxial Diffracted Beams at Transverse Plane and Its Energy Transmission
Abstract:
Based on the vectorial diffraction theory of the angular spectrum representation and taken the nonparaxial diffraction of a small circular aperture as an example,the formulae for three different kinds of light intensity (the conventional intensity I,the power density Jz and the z component 〈Sz〉 of the time-averaged Poynting vector) at transverse plane were obtained.Detailed numerical calculation was performed and the different results were compared.It is pointed out that vectorial property of the light field must be taken into account for the energy transmission of small aperture diffraction.The transmission coefficients of small circular aperture diffraction were calculated respectively by applying the energy flux density vector and the power flux density vector,and some new results were obtained.
