A general self-consistent theory is presented for one-dimensional stat
ionary propagation of relativistically coupled electromagnetic and ele
ctrostatic waves. A finite amplitude plane wave solution is found to b
e always unstable against modulation. A modulated finite amplitude pla
ne wave solution is found in a narrow region of the frequency, and the
possibility for a solitary wave solution and its properties are discu
ssed. (C) 1996 American Institute of Physics.
