Thanks for the reply. It is an electromagnetic source of energy, but this dose not mean that it behaves the same way as a dipole, neither it means that a combination of clock and counterclockwise current loops will give a linear dipole. I am kind of looking for a solid mathematical argument.

I also think that it shuld be just a linear combinition of the two right and left propagating currents that give the solution but I can't derive it mathematically. Any suggestion?

Hello Physics enthusiasts Imagine an infinitesimal small current loop where the current can run clockwise or counterclockwise at frequency v. I am trying to find a linear combination of the two(current loops) which creates the same electric field pattern (far from the dipole) as a very small...

Dear ForumersI am having a bit problem understanding the phase relation between current source and the generated eletromagnetic field components. Assume a very small current element( a very small current running in direction x)(essentially an electric dipole) in a non-homogenous loss periodic...

Hi Guys I have a very simple and basic question. Assume interface of two dielectric mediums. If the t is transmition cofficient for electricfield from medium 1 to medium 2 with refractive indexs n1 and n2, what is the transmitivity of power from medium 1 to medium 2? I know it is...

Could these discussions simply mean that it is not possible to create a field with amplitude 2A by combing 2 waves of A amplitude?! And one more I know that people can create y branch beam splitters using photonic crystals and they get very close to 50% in each arms! But this would then require...

In no sense do I mean to say that conservation law is wrong, That is definitely right. In very simple words what I mean is that superposition principle for electromagnetic fields is NOT consistent with energy conservation law! That is if you double the amplitude of a field you get for times the...

OK so sorry for my previous response but that is due to a previous experience. the scenario I am putting forward is some how different form a simple beam splitter, in that a beam splitter is essential a four port element, two input two out but and it is obvious if you write down the governing...

Ooops. this happened to me once before in this forum too. I aksed a question about CI in quantum dots. A guy popped out of nowhere saying that this is not possible and it is very so and so and I have no understanding of the theory of CI and wasted my time for a while. But later another guy came...

you are simply trying to persuade me that 2+2 is not 4! This is the most basic question to ask in theory and the fact that you give such a silly answer to it, you are simply saying that physics has no answer it, is really unacceptable, I urge you no to answer question you don't know the answer to!

Thx for your reply. But This is not a good answer. In theory you can assume that the two beams are sumed perfectly and have the same phase everywhere.

I have a very basic question about wave interference and more specifically electromagnetic wave interference. Suppose two beams of light each with amplitude A interfere with the same phase. the amplitude of the resulting beam is 2A. the two beams at the start have powers p= A^{2} each. The...

Thanks for your kind replay. I will check them.

I wonder why you inseast that the method is not used and at all wether you have any background or knowldge in solid state calcs. I should inform you that there are many publications where the CI is the method of choice e.g.: Excitonic and biexcitonic properties of single GaN quantumdots...

Well I'm using the single particle states as basis for the integration and am using the product of WF's instead of slater dets to make the comp cost low. But any way I think there is something missing in the formula. I simply inserted the constant wave function (1/v) so the whole integration...
