Hi,
I'm interested in how a dielectric sphere effects a (spatially) uniform time varying field. I'm sure I'm not the first to inquire about this very topic. Could anyone direct me to a resource? Thanks,

Try searching on Mie scattering and Rayleigh scattering.

Thanks Marcusl.
Unfortunately I didn't find what I was looking for. any other ideas?

Dielectric Sphere in Time Varying Field
Hi,
If I have a spatially uniform field whose magnitude is changing in time (say [itex]\vec{E}=E_o\sin(\omega t)\vec{k}[/itex]) and I place a dielectric in this field, will the perturbation of the field have the same frequency? That is, will the resultant field have a frequency [itex]\omega[/itex]?

Yes, assuming that the dielectric has a linear response. This is usually a good assumption unless the field strength is very high (for example, certain crystals are used to double or triple the frequency of intense laser light).
