A Convert to frequency domain

  1. Mar 14, 2017 #1
    Hello All,

    I would like to convert a partial diff equation in time domain into frequency domain, however there is a term of the form:
    Re(∇(E1.E2*) exp(j[ω][/0]t))
    where E1 and E2 are the magnitudes of the electric field and [ω][/0] is the angular frequency.

    Can someone please help me to solve this.

    Thanks for your help!

    Lets see if I understand you so far.
    You have $$f(t) = \Re\left[ \nabla (E_1E_2^\star ) e^{j\omega_0 t}\right]$$ ... and you want to find ##F(\omega)## using a Fourier transform? Is that correct?

    Where do you encounter difficulty? (Please show your best attempt.)
