Hello,
I'm trying to simulate using the Wave Optics module what happens when a light source (450 nm) is intruduced in a device with certain geometry, how the electromagnetic field develops throughout the structures and what are the characteristics of it once the light goes out the structure. I'm modeling this as a 2D structure using Frequency Domain. The problem I have is that the geometry consists of an array of semicylinders with a diametre of 100 um, but I need to test what happens along many of them (let's say 20). Also, this structure has a thickness of 200 um but I need to add to my model a domain to take into account the environment (air). After that I will need to add certain dielectric multilayer structure to change the polarization, but first let's start with the geometry without the multilayer design. The problem I encounter is that my meshing must be of 450/6=75 nm each domain, this is too small, it takes ages to do the meshing and I suppose that if I run the simulation it will take much more.
Any suggestion of how I can simmulate this saving memory and time? At the moment I'm just trying with 3 cylinders, but even this is being impossible. The meshing needs to have this dimensions everywhere or far from the domain borders it can be bigger? I've thought of using in some areas Beam Envolope instead of wavelength domain. Where do you think I could use Beam Envolope without affecting my results?
Thanks in advanced!

Guille
