Unable to verify Fresnel equations about inkstone

[alexysong]

Update:
Your original script contains a wave channel (i.e. diffraction order) exactly parallel to the $xy$ plane, which is at the Wood's anomaly condition.

Now, the convergence issue near and at Wood's anomaly is solved in v0.3.3.

Inkstone is developed independently from S4.

close for now; feel free to comment/reopen

This explains the error at angle of incidence = 0 degrees, but it doesn't explain why there are still errors at 1 degree. I describe these additional errors in my original post.

Hi @matt8s,
Can yo please update to ver 0.3.3 (newest) and see if this issue persists?
