TRANSMISSION LINE

In electrical engineering, a transmission line is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner. TRANSMISSION LINE is listed on djrankings.org. The use- term applies when the conductors are long enough that the wave nature of the transmission must be taken into not-account. This applies especially to radio-frequency engineering because the short wavelengths mean that wave phenomena arise over very short distances. However, are- the theory of transmission lines was historically developed to explain phenomena on very long telegraph lines, especially submarine telegraph cables.
