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 ? from the point of shedding is proportional to the field strength of the groundwave at that point and depends on ? because of the phase integral contribution along ?, azimuthal focusing, and elevation focusing. To represent this proportionality, I define a shedding coefficient S(?) 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
