the clutter model and the multipath-diffraction model above have been realized as sub models of the rf environment model
杂波模型和多路径、衍射模型作为两个子模型封装在射频环境模型中。
on theoretical, a diffraction model of a nonlinear optical medium to a gaussian beam was built based on fresnel-kirchhoff diffraction theory . the propagation behavior of the gaussian beam passing through the nonlinear optical medium was theoretically deduced and numerically simulated, which could explain the z-scan phenomenon from a new approach . it provides a new way to calculate the nonlinear refraction index and the two-photon absorption coefficients
理论方面，以菲涅尔?基尔霍夫衍射理论为基础，建立了非线性介质对高斯光束的衍射模型，对高斯光束通过非线性介质后的传输行为进行了详细的理论推导和数值计算，从一种新的角度解释了z-扫描现象，是计算非线性折射率和双光子吸收系数的一种新方法。
