The Diffraction of Radio Ranges by Hills

Autor: William R. Haseltine

Publikováno v: Physical Review. 57:717-721

The scattering of electromagnetic waves by hemispherical obstacles on a conducting plane has been investigated. The results have been applied to the problem of the splitting of radio range beacons when the range passes over hilly country. The calcula
