    Does anyone know, or can speculate, what effect placing a solenoid
    coil in a high K dielectric such as TiO2 powder would have upon the
    generated composite field?

    A coil in dielectric? Probably negligible, other than interwinding
    capacitance, which could change the self-resonant frequency, but would
    that change even be measurable?

    Why not just try it? (I'm a techie, not an academician - I do hands-on
    tests - when I've used only theory I've never gotten the right answer in
    practice.)

    Another possible consideration: what are the powder's magnetic
    characteristics?

    Cheers!

  3. First speculate on the bulk K of the powder. Even though the individual
    grains might be high K, I would bet the bulk K is not.
