Hi,
Let E(r,t) = E(r)exp(-ikz)exp(iwt)
be a plane wave in time domain, propagating along Z direction.
I wonder how to find the spectral representation of it (i.e. E(r,w))??
I know, for a finite intensity field (i.e. |E(r,t)|^2 < infinity), we can give the spectral representation of the signal by,
E(r,w) = Fourier Transform of [E(r,t)].
But when I do the intergration in Fourier Transform between the + infinity and - infinity, I can't get a solution for above.
Can anyone help me with this?
Thanks
