WAVE GUIDES and GUIDED EM WAVES
We consider/investigate the conditions under which EM waves can propagate when confined to the interior of some kind of “hollow” pipe – also know as a wave guide. In the real world, wave guides consisting of e.g. rectangular, cylindrical, or arbitrarily cross-section shaped conducting and/or superconducting hollow metal pipes can be used to transport EM waves and EM energy in the radio and microwave region of the EM spectrum, whereas, e.g. glass or plastic optical fibers act as wave guides in the infrared, visible and even the UV portions of the EM spectrum.
