WebRadio waves may be propagated in one or more of five modes, depending upon the medium into which they are launched and through which they pass. These modes are: 1. Free space propagation, where radio waves are not influenced by the earth or its atmosphere. 2. Ground wave propagation, where radio waves follow the surface of the earth. WebThe evanescent wave from an optical fiber can be used in a gas sensor, and evanescent waves figure in the infrared spectroscopy technique known as attenuated total reflectance. In electrical engineering, evanescent waves are found in the near-field region within one third of a wavelength of any radio antenna. During normal operation, an antenna ...
