Reply To: Trapezoidal ring

[rahul.sanghvi]

Hi Kirill,

I am working on inverse 3D grating coupler design and I wish to have trapezoidal grates instead of rectangular as provided in the lumerical example. The example uses "addring" to create the rectangular grates in XZ view, but I got many errors when I tried to convert them into a trapezoid. Do you know if there is any easy or an efficient way to do it ?

Many thanks!
Rahul.
