For many years the author is involved with solving scientific and practical problems of using multilayer grating structures in grating couplers, biochemistry sensors, laser resonator modes selection and others. For this reason from the beginning this grating software was designed for personal use to insure a maximum convenience for the user.

Initially the grating software included C-method [1-4] based codes that are very appropriate for smooth grating profile analysis. In 2003 the grating software was extended with True Modes Method [5-9] (TMM) and from 2007 with Fourier Modes Method [10-12] (FMM). The modal methods codes are naturally adapted for the lamellar gratings and are complementary to the C-method based codes. Reliable lamellar modes searching algorithm in TMM and suppression of the FMM instabilities in highly conductive gratings [12] were developed and implemented. From 2008 Crossed-grating (FMM) with an automatic generation of NV-Field [21-23] and from 2010 (C-method [20]) software are available.

Additional features for obtaining results, scanning and optimization were added in 2016 and 2017. Advanced features allow the following:

• To expand the possibility of output for obtained data.
• To extend scanning and optimization features when using any valid combination of the structure parameters. Restrictions only apply to the parameters whose values alter position of other parameters in the text structure (row and column indices).
• To simplify the calculations under the condition of Littrow or user-specified condition, using a valid set of parameters.
