Beam propagation in z direction
As I am a newbie in this program, my question may be stupid or very easy to solve, so, firstly, I apologize myself if this is the case:
I am trying to simulate a photonic crystal using Optiwave. When I perform the tutorials, the final result is the expected one. But, when I try to do mine, I observe that, when I only put an Input field (Gaussian modulated CW; propagation direction +z), a wafer (4×4; material: air) and two observation points (reflected and transmited), in the analyzer I can see that there is Electric field propagating along the Z axis. And I do not know why is this.
What am I doing wrong?
