Basic questions about ewfd in wave optics.

I noticed several examples about waveguides, such as *step_index_fiber_bend *, do not have incentive port. All the boundary is PEC. How come? Where does the electric field or incident wave come from? Is that because ewfd has its own way to excite a wave so we do not need to add one? Thanks very much!
