I am try to repeat a simple simulaiton in a publication ( Effective medium properties and photonic crystal superstructures of metallic nanoparticle arrays).
The sphere diameter is 9.5 nm, and the lattice constant is 20 nm.
the materil follows the Drude model, where omega_p=1.37e16 (1/s), tao=4e-14s.
the surrounding is air. the mesh is 0.5n/grid. The following is the simulation configuration and the reported result
However, in my simulation, I got a lot of nosie (0.5nm). When I used a finer mesh (0.25nm), the noise became worse.
mesh = 0.5nm
I also tried to use stabilized PML layers, the result was as follows
this should be simple simulation. However, I cannot make it work well. I am not sure what is wrong here.
thanks very much for the help.
