TL;DR Summary
Direction of the electric field in a transverse electric guided wave.
Hi,
I have a fairly simple question, but the answer is probably not as simple.
I'm not sure to understand why in a guided wave (TE), the electric field is in the y direction.
I know ##E_z = 0##, but why ##E_x = 0, B_y = 0##?

You will have to give details of the situation you are considering. The orientation of the cartesian coordinates is arbitrary.

Along which axes?

Sorry,
##\hat{x}## is horizontal, ##\hat{y}## is vertical and the direction of propagation is ##\hat{z}##

Sorry,
##\hat{x}## is horizontal, ##\hat{y}## is vertical and the direction of propagation is ##\hat{z}##
Then if ##E_x=0## is because the E field is polarized along y (i.e., it doesn't need to be 0). ##B_y = 0## since it is a TE mode.
