Dielectric Sphere in Time Varying Field

  1. 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.
     
  4. Thanks Marcusl.
    Unfortunately I didn't find what I was looking for. any other ideas?
     
  5. Changing E-field and Dielectrics

    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).
