Wave propagation in a Periodic Segmented Waveguide and the corresponding envelop phase map.

---

---

The waveguide segments are represented by yellow rectangles, the width can be re-sized (click left). It is also repsented the envelop phase of the wave.

Applet parameters :
W : width of the segmented waveguide
W.L. : wavelength
dn : index difference of the waveguide
P : perdiod of the segmentation
DC: period duty-cycle
Length : waveguide length
