 Sep 28 awarded Yearling Apr 16 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.

For my true problem, however, I cannot vary my parameters that way :) Probably I have to work vectorially, then. Sep 8 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! Sep 8 comment Conservation of energy with Huygens-Fresnel principle 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 :) Sep 7 awarded Commentator Sep 7 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?

Aug 31 asked Conservation of energy with Huygens-Fresnel principle Feb 20 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. Feb 16 comment Calculating Kramers-Kronig using Mathematica The formula is the last one on this German Wikipedia article. The English article also explains the backgrounds.
