Quasi-stationary wave propagation

Behind the junction, power of the field propagating within the core increases due to the self-focusing effect, while the pulse duration at the waveguide axis decreases. In the quasi-static approximation, this effect does not depend on the initial pulse duration. Total losses vary with power at the pulse peak similar to the case of stationary wave propagation in the structure A, i.e. they increase with the power (Fig.21, compare with Fig.l 1).

For the case of quasi-stationary combustion wave propagation velocity in a tube with obstacles, the velocity that is obtained due to the flame acceleration, depends on the mixture composition, the tube dimensions and the obstacle geometry. Figure 8.3 [16] presents such a dependence for HAM in 5-30 mm diameter tubes. The blockage ratio in the experiments was BR = 0.39-0.43. 

Apart from the stationary potential patterns just discussed, propagating potential waves under the influence of global (nonlocal) coupling via migration of ions in the electric field are much more readily realized in electrochemical systems [5]. These effects may be most conveniently studied with quasi-one-dimensional systems, that is, ring electrodes where the potential can be recorded at various locations. One example is concerned with the potentiostatic electrochemical oxidation of formic acid on a platinum ring electrode under bistable conditions, as...
