Hello,

I use Lumerical/FDTD Solutions. I can create the array of structures on a line. This array will work as a lens to focus when excited to Gaussian source. However, I want this lens array to have some curves. In other words, I want to create a wavy layered structure for my array of structures that will work as a concave surface for my lenses. Therefore, it can have better focusing effect. How can I start?

Thanks.
