Hi,

I was trying to simulate LC rotation as this link showed [https://optics.ansys.com/hc/en-us/articles/360034915153-LC-Rotation-Simulation-object
], the structure is shown as in fig. 1.


The original paper I try to reperform is
[1] P. Moitra et al., ‘Electrically Tunable Reflective Metasurfaces with Continuous and Full-Phase Modulation for High-Efficiency Wavefront Control at Visible Frequencies’, ACS Nano, vol. 17, no. 17, pp. 16952–16959, Sep. 2023, doi: 10.1021/acsnano.3c04071.


I set the xz plane (out of plane) director orientation for 60 degrees (fig. 2 and 3), but I keep getting this warning (fig. 4). It seems that only in-plane orientation (changing phi) is allowed; whenever theta is set with values other than 0 and 90 degrees, the IDE will give this warning.

I would like to know how to simulate out-of-plane rotation of LC within RCWA. I know FDTD can do this, but the speed is much slower than RCWA.

Thank you for your assistance!

Hi Subscriber,

Thank you for reaching out to us!

Please note that this is the optics forum and not the photonics where lumerical related questions are posted. For your next lumerical question please post at: Ansys photonics forum

Meanwhile I will thransfer this post to the photonics forum.

Kind Regards,

Niki

Dear Subscriber,

Currently, the RCWA solver supports only in-plane anisotropy. Please refer to the RCWA Solver Introduction under the Supported Materials section.
This may change in future versions, so stay tuned for updates.

Best regards,
Kirill
