Hi all,
I know that the electric field generated by a dipole is given by
[itex]\mathbf{E}= [1-i(\omega/c) r]\frac{3 (\mathbf{p}\cdot\mathbf{r})\mathbf{r}-\mathbf{p} }{r^3}+(\omega/c)^2\frac{\mathbf{p}-(\mathbf{p}\cdot\mathbf{r})\mathbf{r}}{r} e^{i(\omega/c)r}[/itex]
where [itex]\mathbf{p} [/itex] is the dipole's dipole moment proportional to [itex]e^{-i\omega t}[/itex].
I'm struggling to find out how this is derived from a Green's function approach. Can somebody help me with this or point me to somebook/reference that shows derivation?
Thanks in advance.
cheers,
Krindik
