The radiation properties of a dielectric sphere with biaxial anisotropy are investigated. The excitation source is assumed to be an elementary dipole of arbitrary orientation illuminated at the centre of the anisotropic sphere. The primary field is defined and computed in terms of the convenient spherical vector wave functions, by solving the wave equation in the phase space. The boundary conditions at the sphere surface are satisfied and following the method of moments, Fourier series and spherical vector wave functions series are employed to express the unknown reflected and scattered fields at the sphere inner and outer region respectively. Although main emphasis is given to theoretical analysis, some numerical results are computed and presented.
