Hi guys,
I want to calculate channel plasmon polaritons dispersion using meep.
I got a dispersion curve of MIM structure but I couldn't got a dispersion
curve of channel plasmon polaritons.
Reference paper is Optics Letters, Vol. 31, No. 23, 3447
And below is my ctl file,
........................................
(set! geometry-lattice (make lattice (size no-size 10 10 )))
(set! geometry
(list
(make block (center 0 0 0) (size infinity 10 10)
(material (make dielectric (epsilon 1.0)
(polarizations (make polarizability (omega 1e-20) (gamma 0.01)
(delta-epsilon 1e+40 ) )))))
(make block (center 0 7 0) (size infinity 10 10) (e1 1 0 0) (e2 0 2.1644
9.763 ) (e3 0 -2.1644 9.763 )
(material (make dielectric (epsilon 1))))
)
)
(set-param! resolution 100)
(set! pml-layers
(list
(make pml (direction X) (thickness 1))
(make pml (direction Y) (thickness 1))
)
)
(define-param k-interp 4)
(define-param fcen 0.6)
(define-param df 1.2)
(set! sources
(list
(make source
(src (make gaussian-src (frequency fcen) (fwidth df)))
(component Hx) (center 0 -2.76 0)
(component Hy) (center 0 -2.76 0)
(component Hz) (center 0 -2.76 0)
)
)
)
(run-k-points 100
(interpolate k-interp (list (vector3 0 0 0) (vector3 1 0 0) ))
)
...........................
Thanks.
Best regards,
Ki-young Choi
