| Abstract: | The magnetic field of spherical particle was deduced under incident plane wave according to the Mie scattering theory.The scattering amplitude function and differential scattered section of spherical particle were transformed from the relative moving coordinate system to static coordinate system by the coordinates and vectors transform.The differential scattered section of spherical particles which had arbitrary velocities were proposed.The theories were self-contained,and the theoretical results were gener... |
