I am trying to create a structure with a straight waveguide on top and a waveguide that tapers upwards on the bottom. I am unsure how to use t correctly, as when I increase the length of the structure, the lower waveguide tapers more and more, which it should not. If it was normalized (i.e. t : [0,1]), I believe my structure should have the same form regardless of length. Can someone help me understand the t variable?
I realized that very shortly after creating this post and tried to delete but could not. Maybe allow a feature to delete posts to save yourself time? Haha, regardless thank you a bunch for the quick response!
