Dear Steven and MEEP's users,
In 2D-PCs: The source will now be the usual Gaussian pulse centered at fcen,
located at one edge of the cell just outside the PML, at x = dpml - 0.5*sx.
Ideally, we would excite exactly the fundamental mode of the waveguide, but it
is good enough to just excite it with a line source. Moreover, since we are
interested in the TE polarization (electric field in the plane), we will excite
it with a Jy current source (transverse to the propagation direction), which is
specified as Ey:
(set! sources (list
(make source
(src (make gaussian-src (frequency fcen) (fwidth df)))
(component Ey)
(center (+ dpml (* -0.5 sx)) 0)
(size 0 w))))
In PC slabs:What do I define the source? Could you help me?
One more many thanks to you!
Yours sincerely,
Chad Huskow
