Hi all,
a few months ago, I asked a question on the mailing list regarding a
function that would describe a sinusoidal dielectric function:

(define (f p)
        (if (> (vector3-y p) (/ (cos (* (vector3-x p) pix2)) (* 2 (/ 1
pitch)))) nbeps xeps))

and then using it like this:

(material (make dielectric (epsilon xeps))

This worked very well.  However, I'd like to describe the material
dispersion using something like this:

(material (make dielectric (epsilon xeps)
        (polarizations 
             (make polarizability
               (omega 0.7227) (gamma 0.10) (delta-epsilon De)))))

However, from meep output, it does not seem to take into account the
polarizability variables.  How could I fix this?  Thanks again,

Nic
