Multi-beam mixing in diffusion-driven media is presented in this paper as a diagnostic for the study of nonplane wave photorefractive interactions. Coupled, nonlinear differential equations are derived which describe the interactions of the intensities as they couple through the medium. These equations were numerically solved using a Runge-Kutta algorithm to gain insight as to how the beams interact in the medium. Three beam interactions in BaTiO3 at 514.5 nm were studied experimentally to verify the analysis. Results indicate that phase aberrations affect intensity distributions in the enhanced beam.

Figure 11Evolution of the integral J, (e, x h;) . ds versus the frequency for D = 9.10-3 Sicm CONCLUSIONWe have studied in this letter the evolution of the complex mode solutions initially obtained for a lossless microstrip line, due to bulk losses introduced in the substrate.Naturally, all the propagation constants of the different modes become complex. In fact, for the conductivity valucs considered (0 i 2 x lo-' S/cm) in this article the two initial complex modes are strongly coupled in the energy sense, and stay much more coupled around the initial complex frequency range than outside so that these two modes cannot exist alone inside this range ( y 2 = -/I2 -inz, /r, and a2 > 0).As the frequency behavior of these two modes are quite similar to the initial complex modes of lossless structures, we have called this pair of modes quasicomplex modes. 3.4. 5. . 7.8.
