摘要：

Mie scattering of an evanescent wave by a dielectric sphere has been theoretically treated by Chew et al. [Appl. Optics 18 (1979) 2679]. We found some discrepancies between our expansion coefficients and that of Chew. The correct analytic expressions are given by reviewing the theory shortly. Furthermore, we investigate the resonance structure and the source function for different decay rates of the evanescent wave. Numerical results are given for the differential scattering cross section and the source function. Source functions for resonant and nonresonant cases are presented for different penetration depths of the evanescent wave.
