*Hello!!
**I am trying to simulate the propogation of a plane wave in a glass of
refractive index 1.47.
But, the png image showed distortion of the plane wave with a bulge at the
center.
When I remove the pml layer in Y direction, I am able to get the plane wave
in the glass. But, by removing the pml we increase the errors in our
simulation. any solution to this problem? Why is the phase of the wave
getting affected due to the pml boundary? *
*
CTL CODE:
*
(set! geometry-lattice (make lattice (size .8 .8 no-size)))
(set! geometry (list
(make block (center 0 0) (size .8 .8 .8)
(material(make dielectric (epsilon 2.1609))))))
(set! sources (list
(make source
(src (make continuous-src (frequency 2.1777)))
(direction X)
(component Hz)
(center -0.3 0)
(size 0 .8 0))))
(set! pml-layers (list (make pml (thickness 0.1)))
(set! resolution 500)
(run-until 10
(at-beginning output-epsilon)
(run-until 10
(at-every .5 output-efield-x)
(at-every .5 output-efield-y))
;(at-every .5 output-dpwr))

Thanks for your time
regards
Ajay
