Abstract : Atmospheric aerosols often contain small inclusions of insoluble material which can affect remote sensing techniques that rely on the scattering or fluorescence for detection, and identification. Thus the exact solution for the scattering from a sphere with a nonconcentric spherical inclusion is derived using an extension of Mie theory. The boundary conditions at the surfaces of both spheres are satisfied by representing the fields emanating from the center of one sphere as a summation of vector harmonics emanating from the center of the other sphere. The exact solution is shown to reduce to the coated sphere solution if the inclusion and host spheres are concentric, and to the Mie theory solution if the refractive indices of the inclusion and host are the same. We then examine the sensitivity of the scattering to various system parameters.
