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:
“Never in the field of human conflict was so much owed by so many to so few.”
—Winston Churchill (1874–1965)
“The failure of academic feminists to recognize difference as a crucial strength is a failure to reach beyond the first patriarchal lesson. In our world, divide and conquer must become define and empower.”
—Audre Lorde (1934–1992)
