Dear meep users,
finally I managed to read my MATLAB results into an array using the C++
interface and I also implemented a function doing a bilinear interpolation.
This allows me to calculate the amplitude of the source at any point in a given
plane. However, I was not able to define a planar source.
volume src_plane(vec(),vec());
makes a nice line source, but I would like to have something similar to
(set! sources ... (center 0 0 lz) (size lx ly no-size))))
in Scheme.
Please, can anyone help me? I am at my wit's end.
Best regards,
Laura

Betreff: Read data to define source
Dear meep users,
it turned out that the simulation of a tightly focused laser beam with an
obstacle in proximity to the focal spot is way more challenging than I thought
it would be. I use MATLAB in order to compute the unperturbed electric field
distribution in a plane at a certain distance from the focus. Fitting these
results seems to be a hopeless task, so I would like to import them into meep
in order to define the amplitude function of my source.
http://article.gmane.org/gmane.comp.science.electromagnetism.meep.general/2286/match=read+data
This article says that reading data into an array is possible using the C++
interface. Subsequently a function is needed that interpolates the points in
the array.
My question is: Can you please give me some lines of C++ code that show how to
read a .mat file (or any other clever file format, for that matter) and, most
important, how to implement the interpolating function.
Any help would be greatly appreciated!
Best regards,
Laura
