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
