How can I simulate microwave 2.45GHz interference in nanoparticles?

I'm using COMSOL to calculate the scattering parameters for a structure of nanoparticles for a microwave with a frequency of 2.45GHz. An error appears in the end of the calculation every time the size of the domain is much smaller than the wavelength. Witch is always the case for me. Is this normal in comsol? How can I overcome this problem?

Even when I try reproduce a plane wave with 12 cm wavelength in an empty space cube with a small dimension, inferior or equal to 10 micrometers the same error appears:

Failed to find a solution.
The relative error (0.37) is greater than the relative tolerance.
Returned solution is not converged.

You will probably find this error as well if you simply decrease the dimensions of the periodic_boundary_condition model.
