Dear all, I am new to MEEP and I am trying to simulate a gold plasmonic scatterer. I am specifically interested in utilizing a 45degrees polarized source (between x and y polarization) or a circularly polarized source in order to excite the plasmonic nanoparticle. What would be the most efficient method to achieve this when using a GaussianSource spanning the entire simulation region (with k_point=mp.Vector3()) and PML boundaries all around. Would another type of source be more suitable? This is my code for an x-polarized source
## Create source # is_integrated=True necessary for any planewave source extending into PML sources = [mp.Source(mp.GaussianSource(frq_cen,fwidth=dfrq,is_integrated=True), center=mp.Vector3(0,0,-0.5*s+dpml), size=mp.Vector3(s,s,0), component=src_cmpt)] ## Create simulation object for empty cell sim = mp.Simulation(resolution=resolution, cell_size=cell_size, boundary_layers=pml_layers, sources=sources, k_point=mp.Vector3(), Courant=courant, symmetries=symmetries, split_chunks_evenly=False ) Thank you very much for your time. Best wishes Nikolaos
