The distance between to neighbouring maxima is ymax.

What makes them particularly useful is the fact that they form a … WebWe present a technique for refractive index sensing using a phase grating structure. A grating under normal incidence can be designed such that the first-order diffracted light travels at a diffraction angle of 90° with respect to the zeroth order. The diffracted light, which is along the direction of periodicity, can further be diffracted from the grating and …
