Hello, dear colleagues.
I'm trying use metal in meep simulate. Below, I put the code with a silver
cylinder.
But the animation shows a strange effect: we see field inside the cylinder
and, some times, 'shots' after the cylinder. Is this correct?
; -------->>>>>> THE CODE
(define-param dpml 1)
(set! geometry-lattice (make lattice (size 16 12 no-size)))
; Ag material
(define a 100e-9) ; define the unit, 100 nm
(define cc (/ (* 2 (* pi 3e+8)) a)) ; unit of frequency in meep
(define wp_ag (/ 1.3798e16 cc))
(define gamma_ag (/ 2.72293e13 cc))
(define Ag
(make dielectric (epsilon 3.7)
(polarizations (make polarizability
(omega 1e-20)
(gamma gamma_ag)
(sigma (* wp_ag wp_ag 1e40))))))
(set! geometry
(list
(make block (center 0 0) (size infinity 8 infinity)
(material air)
)
(make cylinder (center 0 0 ) (radius 3) (height infinity)
(material Ag)
)
)
)
(set! sources (list
(make source
(src (make continuous-src (wavelength 6.5) (width 6)
))
(component Ez)
(center -7 0)
)
)
)
(set! pml-layers (list (make pml (thickness 1.0))))
(set! resolution 20)
(use-output-directory)
(run-until 100
(at-beginning output-epsilon)
(at-every 0.6 (output-png Ez "-Zc bluered"
)
)
)
