Microwave plants are now widely used in industrial and agricultural processes. The main effects by using of focusing of methods in procceses of microwave proccesing of grain cultures is considered. Cereals are dissipative materials with a significant attenuation factor. Focused excitation allows to concentrate field intensity distribution near focusing point in planes parallel and perpendicular to aperture. The limit depth of effective focusing is determined. The dependence of the focus efficiency and the size of the focused area on the depth of the focus point location is also shown.

Keywords: Microwave processing, focusing aperture, efficiency of focusing, size of area of focusing
