应用微扰法研究三层介质构成的微粗糙面光透射问题,推导出不同极化状态透射系数的公式.采用高斯粗糙面模拟实际的分层介质粗糙面,通过数值计算得到底层介质介电常数、中间层介质介电常数和厚度、粗糙面参数和入射光波长对HH极化透射系数的影响.
Optical wave transmission through slightly rough surface of three layered medium is studied. Transmission coefficients with different polarization are derived using a small perturbation method. A Gaussian rough surface is used to describe rough surface of layered medium. Influence of permittivity of layered medium, mean layer thickness of intermediate medium, roughness surface parameters and incident wavelength on the transmission coefficient of HH polarization is discussed.
