The Propagation of Lateral Electromagnetic Waves in Air over Vertical Discontinuities,s dominated—at all but very short distances from the source—by the lateral-wave terms. This is a consequence of the fact that the direct field decays rapidly with distance in lossy media. The lateral-wave field of electric type has the following components in the earth or sea—Region 1 . 0, .—when |.Afflict 发表于 2025-3-30 23:24:21
