Subject: need suggestions in creating EFS
Hi every MPb user.
My name is Andika. I get an assignment to construct EFS in photonic crystal
case. Usually, I use autocad for manual plotting for this task, I found my
previous method is time consuming. . But now, I need to plot EFS by matlab, or
something else. I use following ctl file
(set! num-bands 4)
(set! geometry-lattice (make lattice (size 1 1 no-size)
(basis1 (/ (sqrt 3) 2) 0.5)
(basis2 (/ (sqrt 3) 2) -0.5)))
(set! geometry (list (make block
(center 0 0 0) (size 0.7 0.7 infinity) (e1 0.5 0.5 0)
(e2 0.866 -0.866 0)
(material (make dielectric (epsilon 12.96))))))
(set! k-points (list
(vector3 0 0 0)
(vector3 -0.2887 0.2887 0)
(vector3 -0.236209 0.314945 0)
(vector3 0 0 0)
(vector3 -0.183718 0.341191 0)
(vector3 0 0 0)
(vector3 -0.131227 0.367436 0)
(vector3 0 0 0)
(vector3 -0.0787364 0.393682 0)
(vector3 0 0 0)
(vector3 -0.0262455 0.419927 0)
(vector3 0 0 0)
(vector3 0.0262455 0.446173 0)
(vector3 0 0 0)
(vector3 0.0787364 0.472418 0)
(vector3 0 0 0)
(vector3 0.131227 0.498664 0)
(vector3 0 0 0)
(vector3 0.183718 0.524909 0)
(vector3 0 0 0)
(vector3 0.236209 0.551155 0)
(vector3 0 0 0)
(vector3 0.2887 0.5774 0)
(vector3 0 0 0)
))
(set! k-points (interpolate 100 k-points))
(set! resolution 32)
(run-tm (output-at-kpoint (vector3 (/ 3) (/ 3) 0)
fix-efield-phase output-efield-z))
then, I use contour command in matlab. But, I do not get closed loop curve. .
Please give me some suggestions or guidance in crrating EFS. It wll be a great
help if I get a detail explanation. I will use this EFS to do wave vector
formalisn analysis. I found my previous method is time consuming. in ploting
and converting k-point from reciprocal lattice to x-y basis
