How to generate a tapered waveguide with custom cross section?


Considering some fabrication errors, I want to simulate the transmission performance of a tapered waveguide with a trapezoidal cross section. In other words, this waveguide is tapered in both propagation and vertical directions. But I can’t find any similar example in MODE and FDTD. Is anyone knowing how to build this model?


Dear @lih076

An schematic of design will be quite useful. In the mean time, please take a look at an earlier post in this regard:

The idea is to define vertices, and then use planar solid structure to build the facets. Please take a look at it, and let me know if you had further questions.


Thank you so much. That is what I’m looking for. :grin:
