The Poynting vector for electric and magnetic multipole radiation of arbitrary order (', m) has been obtained, and an expression for the field lines of this vector field has been derived. It is shown that the field lines lie on a cone, and that, for m 6 ΒΌ 0, they exhibit a vortex structure with a di
in which Q is the charge density, connected with the current density by the equation of continuity c -1 div i -----ik~. (2) As is well known, eqs (1) admit one and only one solution that is compatible with Sommerfeld's radiation condition at infinity. This unique solution is conveniently expressed
