Mie scattering for sphere with constant dipole moment

AI Thread Summary
The discussion centers on the existence of a theory for Mie scattering involving spheres with a constant dipole moment. The original poster notes that while there are solutions attributed to Ludvig Lorenz and others, these are not clearly presented in the Wikipedia article, particularly concerning dipoles. They express skepticism about how a constant dipole moment would affect scattering results compared to dielectric spheres, suggesting it does not contribute to radiation. The conversation also touches on the potential impact of the constant dipole moment on polarizability and induced dipole moments, although the need for knowledge of polarizability is emphasized. Overall, the inquiry seeks clarity on the relationship between dipole moments and Mie scattering theory.

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.
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
