Characteristics of the electromagnetic field structure and wave process parameters in the sea tropospheric waveguide

I. L. Afonin, A. A. Bychkov


The paper considers the characteristics of the beam method used for calculation of amplitude distribution of the fundamental wave field inside the sea tropospheric waveguide (TWG) and of the wave process parameters. Expressions are derived making it possible to determine the maximum wavelength of the fundamental mode and of higher modes propagating over TWG. The results of theoretical and experimental investigations are supplemented with a formula for calculation of the “angle of feeding” of natural TWG. The knowledge of this angle contributed to the practical application of such wave-guiding formations.
