- Problem Statement
- Two 1D grating grids are given with period 5a, every slit of them are composed with 5 smaller and square slits with area a**2 with different spatial distribution . I have to calculate interference lost orders due to diffraction for the line q=0.
- Relevant Equations
- derived formulas are written on the paper.
I have calculated the diffraction part for each one of the slits but I am not getting any lost order.
