  1. Radiation forces on a dielectric sphere in the Rayleigh and Mie scattering regime Yong-Gu Lee Reference: Yasuhiro Harada et al. Radiation forces on a dielectric sphere in the Rayleigh scattering regime, Optics communications Vol 124. pp 529-541 (1996) Julius Adams Stratton, Electromagnetic theory, McGraw-Hill Book Company Inc. 1941 Akira Ishimaru, Electromagnetic wave propagation, radiationa and scattering, Prentice-Hall Inc. 1991

  2. Electromagnetic forces on charges and currents Julius Adams Stratton, “Electromagnetic thoery,” pp 96-97, McGraw-Hill Book Company, 1941

  3. Wave optics crash course • Wave equation • Helmholz eqn. • Elementary waves • Spherical wave • Paraboloidal wave • Paraxial wave • Paraxial Helmholz eqn.

  4. Gaussian beam • One simple solution to the paraxial Helmholtz equation provides the paraboloidal wave • Another solution of the paraxial Helmholtz equation provides the Gaussian beam.

  5. Electric-field vector within zeroth-order approximation in a paraxial Gaussian beam

  6. Eqn given in the paper is incorrect

  7. What is the fundamental difference between the Rayleigh, Mie, and Optical regimes? With Rayleigh scattering, the electric field is assumed to be invariant in the vicinity of the particle Taken from the course notes of Radar Metrology by Prof. Bob Rauber (UIUC) http://www.atmos.uiuc.edu/courses/atmos410-fa04/presentations.html

  8. The angular patterns of the scattered intensity from particles of three sizes: (a) small particles, (b) large particles, and (c) larger particles Rayleigh scattering pattern Taken from the course notes of Radar Metrology by Prof. Bob Rauber (UIUC) http://www.atmos.uiuc.edu/courses/atmos410-fa04/presentations.html

  9. p Einc Dielectric Sphere (water drop) incident plane wave A plane wave with electric field Einc induces an electric dipole p in a small sphere. The induced dipole is parallel to the direction of Einc which is also the direction of polarization of the incident wave.
