Effect of an evaporation waveguide on ultrashort-wave propagation over the sea in the line-of-sight and penumbra regions
Abstract
A solution to the problem of ultrashort-wave propagation over the sea is proposed on the basis of invariant embedding method results. Regions of the applicability of various approximate and exact methods are outlined. In the line-of-sight region a simple solution is constructed using approximate methods. In the penumbra region, where the proposed method requires fewer computer resources than existing methods, the significant role of diffraction effects is shown. Calculations are performed to analyze the effect of a surface-based waveguide on ultrashort-wave propagation over the sea in the line-of-sight and penumbra regions.
