To simulate a bent waveguide, it is necessary to define the structure as straight in the geometry. The bend is then specified using the bend_radius parameter within the tidy3d.EMEModeSpec object. In this setup, each EME cell represents a section with the given bend radius, allowing the solver to accurately account for curvature effects. When low losses are expected, it is recommended to use “double” precision in the tidy3d.EMEModeSpec object.
