Thank you, Steven. I will try this of course. However, the mathematical question is still the same. May be I did not formulate it correctly, I will try once again. I have the following structure in the direction of the wave propagation (Z-direction): 1) pml 2) source 3) object (block with a hole) 4) flux plane 5) pml
The distance between each element is fixed excepting 4 and 5. The problem is the following when I change distance between 4 and 5 I obtain different results with flux. Moreover the results seem to be periodical, i.e. if I put the distance between 4 and 5 (let us call it D) equal to 1 (in my units, see ctl attached to the previous letter) I get one spectrum which is almost the same as for D=3, and different for D=2 (which is equal to spectrum for D=4), etc. And that is a real riddle why pml (its better say the distance from pml) influence the data in flux. Even if there is some reflection from pml it should not influence in spectral way (just amplitude may change).
