B. Rothhut,F. Russo-Marie,M. Cousin,D. LandoThe purpose of this chapter is to give you a basic but intuitive understanding of what radio waves are and how radio waves propagate. We will walk through basics of the electromagnetic spectrum and properties of waves as they interact with matter.

Antennas,flow of charge, and voltage, electric potential, to perform their intended function. An antenna can transform an alternating current (AC) into a radio wave and vice versa. In this chapter, we’ll explore the physics that governs how antennas work and how you can use antennas to communicate. We‘ll cov

Project: Satellite Imagery,a real image. Your newfound knowledge of radio theory will be plenty sufficient for you to understand what’s happening behind the scenes. You’ll need a laptop for this chapter, or a desktop very close to a window, as actually capturing data from the satellites must be done outside. Figure 4-1 shows
