  1. The rain area is regarded as a random background medium, and the scattering field and backscattering matrix of the cylinder target in rain are gained. in the coherent case, the power of cylinder target in rain and air and their optimum polarization states are studied by the three - step method

    在研究雨中目標時,本文把雨區看成隨機的背景介質,利用波傳播理論、目標的邊界條件,得出介質圓柱在雨中的散射場、後向散射矩陣,並進行了相關計算。
  2. The casimir energy can be considered as the polarization of the vacuum energy of quantized fields due to the distortion caused by the presence of boundaries, curvature of the space - time manifold or some background fields

  3. In the section 1, we have introduced the background and the recent advance of the flattened gaussian beam ; in the section 2, for the first time, we have calculated the type - i and type - ii shg conversion efficiency and simulated curves versus the crystal length, the pumping light polarization rate, the order of the flattened gaussian beam and the pumped power intensity, we obtain ed that the highest efficiency was influenced by the order and the polarization rate of the pumped flattened gaussian beam

    從三波耦合方程及clbo晶體的光學特性出發,討論了以平頂高斯光束入射時穩態的三波耦合方程的大信號倍頻解(包括類及類相位匹配的倍頻解) 。計算了其在clbo晶體上的倍頻轉換效率與晶體長度,基波偏振分量比,基波階數及泵浦波強度之間的相互影響關系曲線。得出影響平頂高斯光束的最高轉換效率的因素是基波的階數n和泵浦波的偏振分量比d 。
