This is possible due to the consideration of Gaussian beams instead of point sources which allow for the accurate description of not only the laser\&\#x2019;s far-field but also its near-field. The proposed model enables the calculation of the grating period, the inclination and the slant of the grating lines on arbitrarily shaped substrates, originating from the interference of arbitrarily orientated and positioned Gaussian beams.diffraction_grating diffraction modelCommunity for tag(s) diffraction_grating diffraction model
