Hi all,
Can someone provide an example as to how to define the geometry in PyMeep
using meep.material_function?
For the straight waveguide example if I define the waveguide using a
function, how to include it in defining the geometry?
Currently, I wrote
import meep as meep
import numpy as np
from matplotlib import pyplot as mp
sx=16 # size of cell in X direction
sy=8 # size of cell in Y direction
sz=0
cell = meep.Vector3(sx, sy, sz)
# define Gaussian
l=100 # super-Gaussian parameter
sgc=2*l
wmyMaterial=1 # width of the waveguide
def myMaterial(x):
return 12*np.exp(-np.power(x, sgc) / (np.power(wmyMaterial, sgc)))
x = np.linspace(-sy/2, sy/2, 100)
mp.plot(x, myMaterial(x))
mp.title('waveguide')
mp.xlabel('x')
mp.ylabel('Amplitude')
How to use this as the epsilon in meep.medium?
Thanks in advance.
Best regards,
Jisha
