On the base of electromagnetic theory of gratings
we analyse the effects of both of two important parameters of classical blaze grating in Littrow mount to diffraction efficiency
and the two parameters are optimized for obtaining highest diffraction efficiency. It is presented that not only blaze angle but apex angle affect diffraction efficiency. The investigation has been performed on the design and fabrication of classical blaze grating which has high diffraction efficiency. (2012) Trans Tech Publications

The integral theory for electromagnetic theory of gratings
which has complex mathematical tool and long computation cost
is needed to improve computing speed of the algorithm. A very shot-cut equation
which is called symmetrical equation of diffracted wavevectors by us
is presented. It makes the number of Green's function expansion terms shorter and simplifies the integral kernel by taking into account its symmetry. Take the grating in Littrow mount for computing example
because of applying this equation
the computation cost of integral theory which has good convergence
is shorten to 1/2 to 2/5. This work modifies the integral theory and improves its computing speed. (2012) Trans Tech Publications
