Based on huygens - fresnel diffraction integral theory, the propagation properties of bessel beam were studied in this paper. by using the analyses of geometrical optics, hollow beam are found and the formula of the starting point 、 the end point and the bottle length can be got
論文中，我們基於惠更斯-菲涅耳衍射積分理論研究了由軸棱錐產生的貝塞爾光束的傳輸特性，並且通過幾何光學解析無衍射光束的聚焦特性。 -
The fipwa based on electric integral equation ( efie ) is presented firstly, the green ’ s function expansion with sommerfeld identity ( based on bessel kernel ) is studied and the msdp for two cases is formulated. in order to improve the iteration property and avoid inner resonance, the combined field integral equation ( cfie ) fipwa is then constructed successfully
首先研究了基於電場積分方程的快速非均勻平面波演算法，對索末菲恆等式（基於貝塞爾積分核）展開的格林函數進行了深入研究，分兩種情形解決了修正最陡下降路徑的設計問題。 -
The results of the axial and transversal intensity distributions of gaussian beams and 0 - order bessel - gaussian beams show that the results by the optimized laguerre - gaussian truncated series are in good agreement with those by the fresnel diffraction integral method if the integration plane is not close to the aperture
對高斯光束和零階貝塞爾高斯光束的軸向和橫向光強分佈的計算結果表明：當積分面不是很靠近光闌時，用參數最佳化選取的拉蓋爾高斯截斷級數法與用直接數值積分所得結果符合很好。
