The Multiwave Cerenkov Generator(MWCG) is investigated with a two and
one half dimensional(2 1/2 D) electromagnetic relativistic. Particle-i
n-Cell(PIC) simu lation code. Nonlinear beam-wave interaction is consi
dered in the code. Deep insights into the MWCG are demonstrated by sim
ulations. Some of the results agree with those of experiments. The rad
iation is generated with its dominant frequency at 35.5GHz. The power
level of 3.8GW is achieved, with radiation efficiency up to 24 %. The
harmonics of both 71.0GHz and 106.5GHz are observed. The features of p
arameters dependency are presented. And reasonable explanation is put
forward.
