Tropospheric radio propagation assessment

Proceedings of the IEEE, 1985
The status of tropospheric radio propagation assessment is reviewed and recent advances in this area are described. Special emphasis is given to anomalous propagation in a marine environment. Modeling and measurements of ducting phenomena caused by the oceanic evaporation duct and by elevated refractive layers are discussed.

Radio Propagation over Spherical Earth

Proceedings of the IRE, 1935
The paper shows how Watson's solution for the propagation of electromagnetic waves over perfectly conducting spherical earth merges into the Abraham solution for propagation over a perfectly conducting plane for shorter distances. The effects of refraction by the lower atmosphere and of the imperfect conductivity of the earth are taken into ...

Terrestrial Mobile Radio Propagation

2011
The basic principles regarding radiowaves propagation in the mobile radio systems and effects of different phenomena, and parameters on these waves are outlined in this chapter. The issues provided are helpful in design and application of this kind of radiowaves.

Appendix: Radio propagation and radio noise

1999
When a spectrum manager is making a frequency assignment it may be necessary to estimate the minimum transmitter power level that is consistent with the achievement of specified link performance objectives. It is seldom feasible to use direct measure ments for this purpose.

Radio waves and propagation

2003
This chapter discusses properties of radio waves and their propagation. Radio waves are a form of radiation known as electromagnetic waves. The properties of radio waves and the way in which they travel or propagate are of prime importance in the study of radio technology.
