Reply To: how to calculate bending loss using 3D FDTD simulation

[Ahmad Murad]

I'm experiencing a similar issue, so I attempted to follow your instructions for calculating losses. However, I'm still encountering negative values for losses, specifically when analyzing different modes at varying radii. My design involves a bent waveguide, and I'm trying to create a graph that depicts the loss as a function of the bending radius. I would greatly appreciate it if you could explain in detail the steps to achieve this plot
