      I’d like to know if I may make use polar coordinates to simulate circular geometries (in OptiFDTD) to take advantage of symmetry say in simulating a circular grating. How?

      Unfortunately, OptiFDTD does not support cylindrical/spherical FDTD calculations. If the geometry has planar symmetry you can use Electric wall or magnetic wall to reduce the simulation domain by a half.
