waveguide
To act as a [[#Noun|waveguide]] for
waveguide
A structure which guides waves, such as electromagnetic waves, light, or sound waves
waveguide
A device which constrains or guides the propagation of electromagnetic waves along a path defined by the construction of the guide Optical fibres are a form of optical waveguide
waveguide
  A material medium that confines and guides a propagating electromagnetic wave   (188) Note 1:  In the microwave regime, a waveguide normally consists of a hollow metallic conductor, usually rectangular, elliptical, or circular in cross section This type of waveguide may, under certain conditions, contain a solid or gaseous dielectric material Note 2:  In the optical regime, a waveguide used as a long transmission line consists of a solid dielectric filament (optical fiber), usually circular in cross section   In integrated optical circuits an optical waveguide may consist of a thin dielectric film   Note 3: In the rf regime, ionized layers of the stratosphere and refractive surfaces of the troposphere may also act as a waveguide
waveguide
a hollow metal conductor that provides a path to guide microwaves; used in radar
waveguide
In microwave communications, a short (10 feet or less) conductive (metallic) tube that carries very high frequency microwave transmissions from the repeater/amplifier on the microwave tower to the disk antenna
waveguide
A conducting or dielectric structure able to support and propagate one or more modes
waveguide
{i} device used to conduct and direct microwaves
waveguide
Metal tubing used to carry RF signals in the SHF bands between the components of an antenna system Waveguide can be rectangular, elliptical or circular in cross-section and can be smooth or corrugated in its surface The internal dimensions of waveguide are dictated by the wavelength of the frequencies to be carried At SHF frequencies solid conductors cannot be used to carry RF signals due to transmission losses arising from a phenomena known as 'skin effect'
waveguide
A device that transmits waves (e g , sound, light, or radio waves) over a particular path minimizing their tendency to propagate in all directions
waveguide
Hollow pipe (round or rectangular) used as transmission line for the propagation of microwaves
waveguide
Rectangular tube which passes RF energy with very low loss The waveguide cross section determines the operating frequency range, which is about 20 % of the nominal center frequency Waveguide circulators are made with a Y geometry, in which the ferrite is place close to the center of the Y Waveguide flanges are used to connect the device to other components
waveguide
A type of conductor used to carry VHF or microwave energy from one point to another Most waveguides are hollow (rectangular or circular) and carefully dimensioned according to the frequency and energy to be conducted For low-power, short-distance applications a coaxial cable may be used as waveguide Its primary use in radar is in providing a path for the radio energy between the antenna and the transmitting and receiving systems Properly shaped open waveguides can themselves be used as radiators (horn antennas) or as feeds at the foci of reflecting antennas
waveguide
An evacuated rectangular copper tube that provides a path for microwaves to travel along They are very carefully designed for a particular wavelength microwave, so as to transmit as much energy as possible More Information: Waveguide
waveguide
Device that constrains the path of electromagnetic waves (see electromagnetic radiation). It can be used to transmit power or signals in the form of waves while minimizing power loss. Common examples are metallic tubes, coaxial cables, and optical fibres (see fibre optics). Waveguides transmit energy by propagating transmitted electromagnetic waves through the inside of a tube to a receiver at the other end. Metal waveguides are used in such technologies as microwave ovens, radar systems, radio relay systems, and radio telescopes
