摘要：
波在随机连续介质中的传播仍是一个重要的基础问题，应用涵盖从遥感到量子通信。通常，这类介质以平滑的折射率涨落为特征，其对波的影响可由随机抛物型方程描述。后者可通过分步法进行数值求解，该方法用若干源自介质功率谱的离散相位屏替代连续介质。我们引入并对适用于任意功率谱的高精度、高效混合相位屏进行了基准测试，该相位屏基于 Zernike 相位屏与 Fourier 相位屏的结合。
英文摘要：
Wave propagation through random continuous media remains an important fundamental problem with applications ranging from remote sensing to quantum communication. Typically, such media are characterized by smooth refractive index fluctuations whose impact on the wave can be captured by the stochastic parabolic equation. The latter can be solved numerically by means of a split-step method, which replaces the continuous medium with a number of discrete phase screens derived from the medium's power spectrum. We introduce and benchmark highly accurate and efficient hybrid phase screens for arbitrary power spectra which are based on the combination of Zernike and Fourier phase screens.
