Extinction_paradox
In the small wavelength limit, the total scattering cross-section of an impenetrable sphere is twice its geometrical cross-sectional area (which is the value obtained in classical mechanics).[1]
Several explanations for this phenomenon have been proposed:[2]
- destructive interference inside particle shadow[3]
- diffraction and shadowing of light by particle[4]
- superposition of incident and scattered field[5]
- cancellation of incident wave inside particle[6]
