Hi,
You need to include the glass slab into the PML. That is, if sx, sy are the
sizes of the computational box in the x and y direction and you have
propagation along thex direction.
In the case that you dont add PML in the x direction you have PEC boundary
conditions which enforce mirror symmet
Dear Gil,
Try to use longer simulation time.

Dear Steve,
There is a wiki on this mater.

Just put a point source at the desired location. The dft-ldos function will

Dear Steven and Meep users,
I am trying to calculate the LDOS for a periodic medium. Is it correct to
put a single point source and then for a certain k-point calculate the LDOS
via dft-ldos?
However, there is another issue. If this is correct then the total LDOS
should be the sum of the contribu
First, define and normalize to meep units the Drude model plasma frequency
and gamma and then write the following:
(define Ag
(make dielectric (epsilon Ag_epsb)
(E-susceptibilities
(make drude-susceptibility (sigma 1.0) (omega Ag_wp) (gamma Ag_gamma)
)
)
))
Then, you can use 'Ag' as a
Hello everyone!
Is there a way to read refractive index-vs-wavelength data from file and
use it in meep?

First of all, which version of meep are you using?
Here is my code for dispersive Ag:
; Parameters
(define a 100e-9) ; define the unit of length in meters
(define cc (/ (* 2 (* pi 3e+8)) a)) ; unit of frequency in meep
; eV->radpersec
(define (ev->radpersec l)

Do you mean negative epsilon?

I am trying to simulate a LiTaO3 structure using the material parameters
from http://apl.aip.org/resource/1/applab/v85/i4/p543_s1 .
There, omega_T/2pi = 26.7 THz, omega_L/2pi = 46.9THz and eps_inf = 13.4.
Is it enough to divide the frequencies by c/a in order to get the correct
meep frequency uni
