Field Strength

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:

    the whole field is a
    white desire, empty, a single stem;
    a cluster, flower by flower,
    a pious wish to whiteness gone over—
    or nothing.
    William Carlos Williams (1883–1963)

    Whoever aims publicly at great things and at length perceives secretly that he is too weak to achieve them, has usually also insufficient strength to renounce his aims publicly, and then inevitably becomes a hypocrite.
    Friedrich Nietzsche (1844–1900)
