For EM wave, magnetic and electrical components are in phase, meaning when E = 0, then B = 0.
Thus, I understand if it is written:
f(x,t) = A(cos(kx - wt) + icos(kx - wt))
Then why plane wave is always described:
f(x,t) = Aei(kx-wt) = A(cos(kx-wt) + isin(kx - wt))
Implying that Real and Imaginary components are not in phase, which is not the case?
Thank you.
