Dear Meep users, Has anybody performed an analysis of the PML efficiency at oblique incidence ? I am considering a band gap material, and in the gap region the transmission looks fine (1e-6 to 1e-8 values), but the reflection oscillates with the frequency. The oscillation are around the correct value of 1 and their amplitude is about 0.1. My guess is that there is some effective cavity between the sample and the PML which give rise to the oscillations. Their amplitude decreases as with increasing resolution.
So my question is if anybody has had similar experience with PMLs at oblique incidence or if, more general, has looked at the efficiency of the PMLs for absorbing of, say, diffuse light ? Thanks, Marian _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
