Dear meep users I try to make 3d plane wave.
Blow is the program. Here is the visualization of Ex field at z=0.( https://drive.google.com/file/d/1Y0oMyfD5e7xQ7F0jkIz2FC69cKGa3VFM/view?usp=sharing ) When the amplitude become weak, rectangular field comes out from the edges and gather to the center. I think this is strange. Do you know what is this ? Thank you in advance . (set! geometry-lattice(make lattice(size 50 50 24))) (set! geometry (list (make block (center 1 -2 0) (size 4 2 0.3) (material (make medium(epsilon 1))) ) ) (set! pml-layers (list (make pml (thickness 4)))) (set! resolution 6) (set! sources (list (make source (src(make gaussian-src (frequency (/ 1 7)) (fwidth 1))) (component Ex) (center 0 0 7.5) (size 42 42 0)))) (run-until 200 (to-appended "ex-slice" (at-every 0.2 (in-volume (volume (center 0 0 0)(size 50 50 0)) output-efield-x))) )
