Homework Help: Dipole radiation polarization

  1. Apr 2, 2012 #1
    I just have a small question about this dipole matrix element integral,

    http://img827.imageshack.us/img827/6033/37307268.jpg [Broken]

    If you evaluate this integral separately for x, y and z components ( since r = (x,y,z))

    and find that there is only a z component (that the x,y components are zero)

    does having only Pz mean that the direction of the oscillating dipole is the z direction (vertical)?

    And that would mean that the dipole would radiate in the horizontal plane with vertical polarisation right?

    Thanks in advance
