Value n defines the main maximum of the directional pattern which is focused in the direction, perpendicular lines of an arrangement of radiators. This value in n times more, than intensity of the field created by a single radiator in any direction that follows from (at n = in the direction of a chart maximum all intensity of fields of separate radiators develop in an identical phase, i.e. arithmetically.

However, if to be limited to small distances between radiators, equalities (are not carried out and for the considered system only one so-called main maximum in the direction, perpendicular tenches of an arrangement of radiators turns out.

At the mode of standing waves in a wave guide for stronger excitement of a crack its longitudinal coordinate of z has to coincide with antinode of that component of current which crosses a crack. The crack will be equally excited in the mode of the running waves at any value of its coordinate of z.
