Abstract: The propagation of ultrashort electromagnetic pulses with a nonzero electric area in plasma media is analyzed. An equation for the area of an electromagnetic pulse in the one-dimensional geometry has been derived in the unidirectional propagation approximation. It has been shown that this area is not an invariant of motion and can both decrease and increase during the propagation of the pulse depending on the properties of a plasma medium.
