This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The transfer characteristics (amplitude and phase as a function of frequency) of the sky wave propagated between the D-region and the E-region of the ionosphere and the earth have been evaluated at low and very low frequencies by the geometrical-optical theory employing the quasi-longitudinal approximation of the ionosphere reflection coefficients. Distances, d/j, up to 1000 statute miles are considered and multiple hops or time-modes (j = 1, 2, 3, ... ) are evaluated for a vertical electric dipole source. The effects of the electron density, collision frequency, intensity of the earth's magnetic field and the geometrical parameters are illustrated. The effect of the vertical lapse of the permittivity of the earth's atmosphere is introduced into the computation.

Download or read book Radio Wave Propagation for Telecommunication Applications written by Hervé Sizun and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the physical mechanisms involved in the propagation of electromagnetic waves in the radiofrequency range, inside and outside buildings, in the terrestrial and near space environments, with a special focus on mobile radio communication. It combines a theoretical and an experimental approaches with an understanding of the physical environment through adequate formulations of the laws of electromagnetism. It should thus provide the background needed by advanced students and development engineers for the conception of high quality and reliable telecommunication systems.

Download or read book Characteristics of the Earth ionosphere Waveguide for VLF Radio Waves written by James R. Wait and published by . This book was released on 1964 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal results of this technical note are graphical presentations of the attenuation rates, phase velocities, and excitation factors for the dominant modes in the earth-ionosphere waveguide.The frequency range considered is 8 kc/s to 30 kc/s. *The model adopted for the ionosphere has an exponential variation for both the electron density and the collision frequency, and the effect of the earth's magnetic field is considered.Comparison with published experimental data confirms that the minimum attenuation of VLF radio waves in daytime is approximtely at 18 kc/s, while at night it is somewhat lower.The directional dependences of propagation predicted by the theory are also confirmed by experimental data.(Author).
