Abstract:

The waves in the spherical guide between the earth and ionosphere are excited by a horizontal electric dipole. The guide boundaries are characterized by surface impedances, and the resulting waves are expressed as a superposition of TM and TE modes. The wave numbers, excitation factors, height-gain functions, and height-dependent impedances are examined for both types of modes. Author
