The radiation force on a sphere illuminated by the TEM81 mode laser beam was ray-optically treated by Roosen, Louvent and Slanskyl, and Kim and Lee2 developed a theory of radiation force on a homogeneous sphere in the Hermite-Gaussian mode laser beam by using the incident field, of which the expression is an exact solution of the wave equation. The radiation torque on a sphere in the circularly polarized plane electromagnetic field was theoretically worked out by Marston and Crichton3 and Chang and Lee 4 derived the formulas of radiation torque on a homogeneous sphere levitated in the circularly polarized TEM00 mode laser beam. However, for a stratified sphere illuminated by the focused TEMoi mode laser beam a further development of the formulas of radiation force and torque is required and the light scattering theory by a stratified sphere needs to be extended.
