General wave behaviours along uniform guiding stru ctures As depicted in Fig. 2, a time harmonic field propagating in the z direction of a uniform Propagation in Lossy Rectangular Waveguides and = , Transmission lines such as microstrip, coplanar waveguide, stripline or coaxial cable may also be considered to be waveguides. The electromagnetic waves in a (metal-pipe) waveguide may be imagined as travelling down the guide in a zig-zag path, being repeatedly reflected between opposite walls of the guide. In a sense, all transmission lines function as conduits of electromagnetic energy when transporting pulses or high-frequency waves, directing the waves as the banks of a river direct a tidal wave. However, because waveguides are single-conductor elements, the propagation of electrical energy down a waveguide is of a very different nature than The technology is based on an Artificial Magnetic Conductor that enables contactless propagation of electromagnetic waves, significantly reducing transmission losses. Antennas based on Gapwaves waveguide technology have over 10 times lower losses than microstrip lines, over 3 times lower losses than SIW, and approximately the same losses as The propagation of transverse electric (TE) and transverse magnetic (TM) waves in a waveguide of arbitrary cross section with an anisotropic periodically space-and time-modulated insert is Propagation of electromagnetic waves in a waveguide with a modulated anisotropic insert | SpringerLink Abstract: We study long range propagation of electromagnetic waves in random waveguides with rectangular cross-section and perfectly conducting boundaries.
