Viga Rajiman,Hairul Nazirah Abdul Halim ionosphere did not exist: 1) Analytical fullwave solutions exist only for particular geometries. The solution for a spherical geometry (i.e., a homogeneous, isotropic, concentric, sharply-bounded ionosphere) has been particularly well developed [WATSON, 1919; BREMMER, 1949; WAIT, 1960, 1961; JOHLER

Viga Rajiman,Hairul Nazirah Abdul Halim distance ℓ from the point of shedding is proportional to the field strength of the groundwave at that point and depends on ℓ because of the phase integral contribution along ℓ, azimuthal focusing, and elevation focusing. To represent this proportionality, I define a shedding coefficient S(ℓ) equal

Groundwave excitation and shedding coefficients are evaluated by comparing the GTD solution for the field of a vertical Hertzian dipole over a homogeneous, isotropic, spherical eart

Jede Mode der Bodenwelle wird durch einen oberflächengebeugten Strahl in einer komplexen Höhe, die durch die Ausbreitungskonstante der Bodenwelle bestimmt ist, dargestellt. Die Anregungs- und Ablösungskoeffizient en der Bodenwelle werden durch Vergleich der GTD-Lösung mit der
