Mie scattering for sphere with constant dipole moment

Click For Summary
SUMMARY

The discussion centers on Mie scattering theory as it pertains to spheres with a constant dipole moment. Participants reference the foundational work of Ludvig Lorenz and express confusion regarding the application of Mie theory to dipoles, particularly in relation to dielectric spheres. It is concluded that while a constant dipole moment does not contribute to radiation, it may influence polarizability and the potential for induced dipole moments. The need for further exploration of these concepts is emphasized.

PREREQUISITES
  • Mie scattering theory
  • Understanding of dipole moments
  • Concept of polarizability
  • Dielectric materials
NEXT STEPS
  • Research Mie scattering applications for dipole moments
  • Study the relationship between polarizability and induced dipole moments
  • Explore the effects of particle rotation on scattering outcomes
  • Investigate the historical context of Ludvig Lorenz's contributions to scattering theory
USEFUL FOR

Physicists, optical engineers, and researchers in materials science focusing on light scattering phenomena and dipole interactions.

Hi

does anybody here know whether there already exists a theory that describe Mie scattering for spheres that have a constant dipole moment?
 
Science news on Phys.org
According to the Wikipedia article, there are solutions (Ludvig Lorenz and others), but they are not shown in the article.
 
where exactly? i only see this name when it comes to dielectric spheres, not dipoles?
 
I don't see how a constant dipole moment should change the results (compared to the dielectric sphere), as long as it is constant it does not contribute to radiation. If your particle has enough time to rotate, it becomes tricky, but I think that would require really weird intensity/frequency/particle combinations.
 
well, i thought that maybe the constant dipole moment has an effect on the polarizability and therefore on the possibility to have induced dipole moments.
 
Maybe, but you have to know polarizability anyway.
