Symmetry

• Why is it preferable to use symmetry whenever possible?
• How do I set symmetry in Tidy3D?
• How do I identify the symmetry planes of my simulation?
• What does “odd, i.e. ‘PEC’ symmetry” mean?
• What does “even, i.e. ‘PMC’ symmetry” mean?
• How do I filter out waveguide modes using symmetry?
• Does Tidy3D support continuous and discrete rotational symmetries?
