Antenna Briefs 7 - Radio Wave Reflections in Propagation and Antenna Design - Part 1 of 2

This episode covers reflection of radio waves and how it is important in both propagation, and in the design and construction of directional antennas. Part 1 overviews both, as well as introducing related effects including refraction, diffraction, absorption, and scattering. The main focus is at frequencies of VHF and above, including cellular, but a brief mention of HF propagation is also made. Part 2 will provide an overview of how EM fields are reflected (and/or absorbed) by materials including metal and wood, and show real-world measurements of reflection and absorption (attenuation) for some typical materials found in residential and commercial buildings.

Another great episode, full of easy to understand information. If you are interested in this subject, I recommend you watch the whole series. It will be time well spent.
