Calculation of the attenuation factor while propagating the vertically polarized radio waves of a meter range above sea surface by the Fock’s method

An investigation of the meter radio waves diffraction attenuation on the underlying sea surface, is performed. Solution of a differential equation for determining the Airy’s function roots is obtained, calculations of the attenuation factor are carried out for various conditions of radio wave propagation. The distant relationships of the attenuation factor are given for various propagation conditions of radio waves. Definitions of a lit area and of a penumbra area are given, as well as a possibility of these areas’ extent calculation.
