Abstract: Scattered light from particles near a plane interface has important implications for many branches of science. Applications range from radar detection and remote sensing to clean-room monitoring and quality control in the manufacture of silicon wafers. The most fundamental system of this type is that of a sphere near a plane interface. Calculating the scattering is complicated because the boundary conditions at the sphere and plane surfaces must be satisfied simultaneously, and these two systems represent two fundamentally different geometries. In this report we present an analytical solution to this problem that retains the physics and may be used as a basis for more numerically intensive techniques necessary when the system constituents become irregular.
