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
