Hertzian dipole generating EM Waves.

  1. May 22, 2007 #1
    Hi, in my notes for the Hertzian Dipole I have a derivation of the vector potential A, and the scalar potential (phi). However, i'm missing the derivation of the E and B fields from these potentials. It seems that only the theta component of the E field exists, and I have ... well, I can't write it out because I don't how to use the webcode to equations... but it has omega, I0 (current), sin(theta), and another sine term, but with an argument that is omega x the retarded time.

    Anyone got any clues? Or even an idea of what I'm trying to say? (I realise the question is a little sketchy)

    If you've got the vector potential, take the curl to get the magnetic field? I don't see where the problem is.
