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:
“She is as in a field a silken tent
At midday when a sunny summer breeze
Has dried the dew and all its ropes relent,”
—Robert Frost (1874–1963)
“His strength is so tender, his wildness so meek,”
—James Russell Lowell (1819–1891)
