farfield


Also found in: Dictionary, Thesaurus, Medical, Wikipedia.

farfield

A far distance. It typically refers to the propagation of electromagnetic waves over long distances. Depending on the application, farfield may be contrasted with "nearfield" (short range) or with "midfield" (in between). See nearfield.

Fleischman and Reed's Farfield Foundation was a Central Intelligence Agency (CIA) "dummy front," meaning it was set up as a legal foundation, though the only funds it had were provided by the CIA.
Figure (a) and (d) are recorded at farfield -z and +z positions, where the nonlinear effects are absent due to low intensity.
En 1967, cuando el Congreso perdio su credibilidad porque quedo al descubierto "como beneficiario de fondos de la cia desde la decada de los cincuenta" (Bloch, "La guerra de Vietnam" 32), "Margaret Shedd continuo sus relaciones con la Fundacion Farfield, el frente de la cia".
Thus we chose different values of intensity on the farfield frontier of the computational domain, this is seen as a replacement for the practical case where a turbulence inducing grid or obstacle would typicaly influence the flow upstream.
Farfield potential responses reflect structures with a diffuse signal to a larger area of the surface, they are more likely to be detected at multiple electrode sites.
La Fundacion Farfield y la Fundacion Ford salieron al encuentro del Congreso para financiar, en 1960, el 50 aniversario de la muerte de Tolstoi al que asistieron escritores como Franco Venturi, Iris Murdoch, Herbert Read, Alberto Moravia, George Kennan, Jayaprakash Narayan y John Dos Passos.

In general, the farfield of an antenna is the Fourier transform of its near field [16,17].
Hence, conformal mapping preserves the farfield radiation-patterns verified in Figures 5 and 6.
