comment Calculating Kramers-Kronig using Mathematica
No, different problems with the same code. Not talking about the necessity to dig that up more than one year later.

comment Intensity of the diffraction pattern of the double slit
So you agree that this example from the book is flawed? For my true problem, however, I cannot vary my parameters that way :) Probably I have to work vectorially, then.

comment Conservation of energy with Huygens-Fresnel principle
Sorry, I made a mistake defining my elementary wave - or better: Here I took it from the calculations and it differs from my normal version (where x and x0 are the vectors for the center and the current position). I should have checked that again :) Concerning the geometry: The first part is linear, while the code is circular. I should have made that more clear. I am working linear ATM, for the full intensity, I changed it to circular, to keep everything finite. I will check everything when I am back in my office on Monday, as I need a licence server for Mathematica. Thanks!

Oh, great. After I did not really get forward with the Jackson Electrodynamics, that book would have been my next try. It is already lying on my desk in my office for Monday :)

comment Conservation of energy with Huygens-Fresnel principle
I am not sure I understand what you mean. A(x0,x0) is infinity, isn't it? The elementary wave is already normed in a way way that each wave has the power of 1 (integral of |A| of a circled centered at the source of the wave). That's why I wrote I expected a combines power of, as w=2 (but the slit radiates in two direction, so it reduces to 1). However, I do not understand why I should scale my result with that again. Could you expand your answer, per chance using the latex syntax?

Cleaned up a bit, tried to clarify the problem and added new code.

comment Calculating Kramers-Kronig using Mathematica
I am integrating by $\text{d}\lambda$, but also, my denominator is ((2 Pi c 10^9 /li)^2 - (2 Pi c 10^9 / ln)^2). - But I forgot to do the substitution for $\text{d}\Omega$. Dammit, awkward.

The formula is the last one on this German Wikipedia article. The English article also explains the backgrounds.
