We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hello Hrishikesh, Thanks for your reply and sharing your model. As I suggested in a previous post of mine, I would recommend to extend the span of the source through the FDTD simulation boundaries. Please refer to the following articles: https://optics.ansys.com/hc/en-us/articles/360034382874-Understanding-field-truncation-issues-with-finite-sized-plane-wave-sources. https://optics.ansys.com/hc/en-us/articles/360034382854-Plane-wave-and-beam-source-Simulation-object I hope I helped. Please let me know if you need further assistance. Kind regards Dimitris
