Thank you!

Thank you for the answer! What do you mean by dropping the kb and the h? I mean, we can not just drop them without paying attention to the units that they are expressed in. What should I do to turn the K-frequency into the sec--frequency in this situation? Still a little bit confused.

Hey! In https://www.researchgate.net/publication/230937856_Optical_properties_of_graphene article (Optical properties of graphene) I found out the frequency is expressed in Kelvins. Could you help me with it - how did the author do this unit transformation? Thanks in advance!

Hello! CST modelling.

Hello! What do you mean by mono-layer photons? It is a transition radiation problem, withing macroelecrodynamics theory, that is all :)

Hello! I would like to ask about any software package, where interaction between a moving particle and a monolayer can be simulated. What i need to get is a spectral angular density distribution in the far-field zone within optical frequency range for a problem when a particle crosses a...

Hello! Can you give me an advice about a program (free program probably) where i can program an animation of a moving particle along some surface for a presentation? Now I'm trying to use Animate in Wolfram Mathematica, but it is not, what I'm looking for from the design point of view... Thank you!

i think 2K0() is more appropriate here, because in particular case of a=0, the result will be 2K0(b)

no, b and a are real. i meant that k = +-ib.

Thank you, wrong paper i was looking through.

are you sure about the title of the article? i can not find that piece that you are referring to. besides the integral (10) has a singularity on Re axis, not on I am like mine one has.

Thank you! I'm trying to calculate radiation arises when a particle moves along the shaped surface. I've looked through the articles and i want to know what transformation do you exactly mean, specific polar coordinates? I guess if the result would be πiH10(ib|a|) or 2K0(b|a|) Wolf.Mathematica...

Hello! I've got unexpected problems with this very integral. I've looked through "gradshteyn and ryzhik" and found similar, but not the same. So the result, as i think, will be Bessel functions or so. Wolfram Mathematica could not calculate it, so i thought you would help with it, because it...

Hello! There is a problem with Mathematica: i calculate an integral with a help of NIntegrate and get the whole list of spherical coordinates, like {6.24, 3.14, 0.323488}, {6.26, 3.14, 0.323488}, {6.28, 3.14, 0.323488} and so on... then i create a list, like data = List[{6.24, 3.14, 0.323488}...

yes, but what about the spiral curve and it's shape? that's right, but i don't have it because field itself is the electron field and radiation field. And to find the last one i have to solve Maxwell's equation first and then do the next step whatever it is. The thing is that to find...
