摘　　要：用半解析半数值的方法求解了平面波在任意连续分层介质覆盖导体球上的散射问题,作者用位函数表示平面波,再将位函数分解成球面波,其球面波在分层介质上的散射将被化成一个两点边值问题,给出了边界条件和统治方程,可给出其散射系数.The scattering of plane wave from conducting sphere coated with continuously layeredMedium is studied by semi-analytic and semi-numerical method. The plane wave is expressed in potentials. The potentials are decomposed into spherical waves. The scattering of spherical waves from a conducting sphere coated with continuously layered medium is reduced to a two-point boundary value problem. The boundary conditions and governing equations are given. The scattering coefficients are given.
