Electromagnetic question

  1. Sep 17, 2005 #1
    Dear friends,

    I'd like to know if there exists an electromagnetic wave that magnetic field is not perpendicular to electric field.

    If you have a "regular" EM wave, with E perp B,
    then add a uniform constant E-field in the region,
    the resulting E is no longer perpendicular to B.

    Or are you looking for a "less trivial" situation?

    Hello lightgrav:

    I'm looking for this posibility, if there's probably or simply teoretical possible that one electro-magnetic wave could have his components not orthogonal. If not, if there's any type of wave that could be this way.
