Nonlinear mixing of microwaves in a plasmafilled waveguide
Abstract
The phenomenon of nonlinear mixing of two microwave beams of nearly the same frequency (omega 1, omega 2) and the generation of omega 1 + or  omega 2 frequency waves has been studied in a rectangular waveguide. The nonlinearity arises through the ponderomotive force on electrons. It is seen that the yield of difference frequency generation is much larger than that of the sum frequency generation. This suggests that submillimeter waves may be efficiently generated by mixing two laser beams.
