Book excerpt: The addition of phase difference measurements to partial reflection experiments is discussed, and some advantages of measuring electron density this way are pointed out. The additional information obtained reduces the requirement for an accurate predetermination of collision frequency. Calculations are also made to estimate the errors expected in partial-reflection experiments due to the assumption of Fresnel reflection and to the neglect of coupling between modes. In both cases, the errors are found to be of the same order as known errors in the measurements due to current instrumental limitations.

Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the 21st century the world still faces various global environmental issues. Examples include the rise in atmosperic temperature due to the increase of atmosperic carbon dioxide, the depletion of the ozone layer and El Nino related climatic anomalies. Remote sensing technologies that use electromagnetic waves are quite useful in measuring physical parameters which describe global environments. This book covers the theory of electromagnetic remote sensing and the basic technologies used.

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).

Available in PDF, EPUB and Kindle. Book excerpt: This bibliography comprises a non-exhaustive compilation of over 1400 references to the world's literature in the ionosphere with special emphasis on its effect on reflection, refraction or propagation of electromagnetic waves. The frequencies involved are usually in the low frequency or long wave bands in contrast to those (UHF, VHF and SHF) involved in tropospheric propagation investigations although the pulsed technique at vertical or slant incidence makes use of a wide range of frequencies.
