Dear all,
I'm trying to solve Maxwell electrostatic surface integral equation,
lambda*U(r) = 1/(2*pi)* Integrate( U(r') (r-r')/(abs(r-r'))^3 ds)
for a sphere. Lambda is an eigenvalue and the integration is over the surface of the sphere. I used weak form boundary (wb) module as mentioned in (www.comsol.com/community/forums/general/thread/3389 ) by Marc Jouan. I used boundary free mesh and solved for eigenvalues near 0.
However, the results I'm getting is quite different from the known Mie theory results. ( The lambda for lowest dipole mode should be around 0.333). But here result doesn't even give a dipole.
It seems this is a very simple simulation but, even after so many efforts I still cannot figure out what goes wrong here. Please can any one be kind enough to look at my model and give some feed back. I have also attached the example given in above link.
Thanks in advance
