Propagation Mechanisms The higher frequency The more radio waves resamble the properties of light At lower frequencies Electrical properties of obstacles are important (but we tend to express these in terms of optical properties) If the wave length is of the same order of magnitude (or larger), ...

2. HF Communications 2.1 Types of HF Propagation High Frequency (3 to 30 MHz) radio signals can propagate to a distant receiver, Figure 2.1, via the: ? ground wave: near the ground for short distances, up to 100 km over land and 300 km over sea. Attenuation of the wave depends on ...
Waveguides The wave propagation along the waveguide is described by from which the differential equation describing the electric field along the waveguide axis is found to be whose solution is Waveguides There are two regimes for waveguide operation: The special value of the wavenumber kc is the cut...
