dipole fdtd
I'm not sure how to describe oscillating electric point charges in FDTD scheme of the time domain Maxwell equations, but I would like to model the near-fields produced by an oscillating electric dipole and electric quadrupole. Then I will compare these solutions to analytical ones. I think a dipole could be just represented as a point current and then in one FDTD grid set a hard source as
Ex(i,j,k) = dt*sin(omega*t)/eps0
I'm not sure if this is correct. How about a quadrupole then?
