In physics, the field strength of a field is the magnitude of its vector value.
In theoretical physics, field strength is another name for the curvature form. For the electromagnetic field, the curvature form is an antisymmetric matrix whose elements are the electric field and magnetic field: the electromagnetic tensor.
In radio frequency telecommunications, field strength is the magnitude of the received electromagnetic field which will excite a receiving antenna and thereby induce a voltage at a specific frequency in order to provide an input signal to a radio receiver for such applications as cellular, broadcasting, wi-fi and a wide variety of other radio-related applications.
Famous quotes containing the words field and/or strength:
“Love to chawnk green apples an’ go swimmin’ in the
lake.—
Hate to take the castor-ile they give for belly-ache!
‘Most all the time, the whole year round, there ain’t no flies on
me,
But jest ‘fore Christmas I’m as good as I kin be!”
—Eugene Field (1850–1895)
“To ask strength not to express itself as strength, not to be a will to dominate, a will to subjugate, a will to become master, a thirst for enemies and obstacles and triumphant celebrations, is just as absurd as to ask weakness to express itself as strength.”
—Friedrich Nietzsche (1844–1900)
