Dear all, I am testing with MEEP 3D a long thin dielectric taper along a dielectric waveguide junction (a double configuration in fact, to have a continuous waveguide-taper-system-inverse taper-continuous waveguide setup). I have one flux sensor in each span of continuous waveguide, and the "input" sensor is at a few lambda's from the point source, as normal.
The introduction of the taper (a simple wedge shape obtained by subtracting rotated and rescaled versions of blocks of "air" from a block of higher index medium) creates anomalies in the output flux: NANs, tens of orders of magnitude of difference in power. As I noticed, the tips of the tapers are smaller than a voxel, so they become "grey" after the subpixel smoothing step. Anyone has an idea about this? Any feedback will be much appreciated; Marco Zocca _______________________________________________ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
