"Planewave Sources Extending into PML" not possible with meep version 1.23.0

[linaku94]

I want to create a plane-wave source extending into a PML-Layer. Therefore, I tried to reproduce this tutorial/example

I used the exact same code:

import meep as mp
import matplotlib.pyplot as plt

pml_layers = [mp.PML(thickness=1)]
cell_size = mp.Vector3(10,10)

sources = [mp.Source(mp.ContinuousSource(1,is_integrated=True),
                     center=mp.Vector3(-4),
                     size=mp.Vector3(y=10),
                     component=mp.Ez)]

sim = mp.Simulation(resolution=20,
                    cell_size=cell_size,
                    boundary_layers=pml_layers,
                    sources=sources,
                    k_point=mp.Vector3())

sim.run(until=30)

sim.plot2D(fields=mp.Ez)
plt.show()

However, the is_integrated option doesn't change anything, I never get an actual plane-wave source. My meep version is 1.23.0, but the same issue appears with 1.22. With version 1.21 it works.

resulting figure, is_integrated = True with meep 1.23.0

Thanks for the bug report! git bisect says that the problem is due to ce4d151 (#1829) by @oskooi

It looks like that PR added some is_integrated=False defaults to subclasses for documentation purposes, but forgot to pass the user's value to the superclass constructor.

Should be fixed now on the master branch.
