The transverse energy fluxes (both instantaneous and averaged) arising under the superposition of two quasi-plane waves are considered in this paper. The case of superposition when the frequencies of the interacting beams are different is analyzed. The cases of superposition of coaxial orthogonally (linearly and circularly) polarized waves are considered. The mechanisms of forming the distribution of characteristics of the resulting averaged transverse component of the Poynting vector are established. The data of computer simulation are presented.
The superposition of two plane waves with different frequencies and different polarizations is considered. It is shown that electrical vector moves along complex trajectory, which is similar to the Lissajous figures. The characteristics of possible trajectories are analyzed. The results of computer simulation are presented.
The possibility of formation of the beam with edge dislocation, which is similar to the ТЕ<sub>01(10)</sub> beam is considered. It is shown that such mode may be obtained due to the diffraction of plane wave on the complex Bragg hologram, constructed as composition of two grating recorded on the same place of registration media. These partial holograms are implemented as the gratings with constant period and close characteristics. The conditions of such operation are formulated. The experimental results are presented.
