Reply To: I want to mesaure the transmission for the given unit cell

Hello,

Thanks for your question. Could you please provide some more information about the effect you wish to model? Are you trying to reproduce a figure from a paper that can be referenced?

It looks like this device may be a microwire polarizer or plasmonic device. In that case, we have a few relevant application gallery examples. If any of these are similar to the device you are trying to model, it may be easiest to start from one of these example files and modify it according to your simulation:

• Microwire polarizer – Ansys Optics
• Polarization-Sensitive Plasmonic Reflectors for HUD – Ansys Optics
• Tunable THz metamaterial based on a periodic array of graphene – Ansys Optics

I can also suggest a few suggestions for troubleshooting. Firstly, it can be very helpful to use a movie monitor to visualize the fields. This can help to identify any obvious errors (for example, if the light is injected in the wrong direction). Since this is a periodic device, I would recommend using Periodic boundary conditions along X and PML conditions along Z. Most likely, the source should be a plane wave, and the option to set the polarization of that wave is in the plane wave source settings. If you wish to inject the light at an angle, then you will need to use Bloch instead of periodic boundary conditions. 

I hope this information is helpful. If you are able to share any results from your simulation, that may help with troubleshooting. 

Best,

Anna
