    Hello Maria,

    You will need to provide more information for others to be able to help you. What type of diffraction grating are you attempting to design? What specifications are you working with?

    To help get you started we do have two lessons on diffraction gratings:

    Hi Scott,

    I viewed at the two links you supplied: Is it possible to view the diffraction angles also for 3D simulations?

    Hello Christopher,

    I am not certain what version of the product you are using but the newer versions of the product do include a 3D far field calculator which allows you to visualize how the field propagates in 3D. This would be located in the OptiTools product that comes installed with OptiFDTD.
