angle of radiation

angle of radiation

[′aŋ·gəl əv rād·ē′ā·shən]
(electromagnetism)
Angle between the surface of the earth and the center of the beam of energy radiated upward into the sky from a transmitting antenna. Also known as angle of departure.

Color temperature 5000k angle of radiation: 120grad power consumption: not higher than 18.
The degree to which an object emits is characterized by its emissivity which is a function of the dielectric constant, the incident angle of radiation and the polarization like Fresnel's reflectivity [3].
The researchers used an easy-to-see reference--the alignment of jets of radio waves emitted by many of the quasars and galaxies in their study--to measure the polarization angle of radiation. Because polarization is generally thought to start out perpendicular to the jet direction, any extra rotation, or twist, in the polarization of light should be readily apparent, Wardle and his colleagues assert.
The angle of radiation was "rostral" when the rays made an angle of [less than]45 [degrees] with the longitudinal (snout-to-tail) axis of the animal.
In this way, sun exposure was maximal (100%) and angle of radiation was dorsal.
