Hello MEEP Users and Steven,
I've calculated meep about fiber
meep can use cylinderical coordinate system (r,z)
range is 0=<r <= rmax
range is 0=<z <=zmax
r=rmax
|
|
|
|
|
|________________________
r=0 z
so.. that mean (fiber)
r=rmax
___________________________
|
|
|
|
|
|________________________
| r=0 z
|
|
|
|
|_________________________
in example source
f.add_point_source(Ep, 0.25, 3.5, 0., 8., veccyl(rmax*5/6+0.1, zmax/6+0.3), 1.);
source locate no zero point (r=0)
so I put located at r=0
but beam propagation was wrong!!
Beam intensity was decrease ..
what's wrong?
