Abstract. A fast travelling-wave Mach-Zehnder modulator is modelled and designed using a rigorous vectorial analysis. In order to investigate propagation characteristics, velocity and microwave loss, the semiconductor layer stack and the lossy electrodes are modelled using the method of lines. The microwave field distribution is determined, design curves are derived and the cross-sectional dimensions of the modulator are optimized. The loss of the fabricated device agrees very well with small signal measurements up to 40 GHz and HFSS simulations.

We consider a two-step Sal’nikov reaction scheme occurring within a compressible viscous gas. The first step of the reaction may be either endothermic or exothermic, while the second step is strictly exothermic. Energy may also be lost from the system due to Newtonian cooling. An asymptotic solution for temperature perturbations of small amplitude is presented using the methods of strained coordinates and multiple scales, and a travelling wave solution with a sech-squared profile is derived. The method of lines is then used to approximate the full system with a set of ordinary differential equations, which are integrated numerically to track accurately the evolution of the reaction front. This numerical method is used to verify the asymptotic solution and investigate behaviours under different conditions. Using this method, temperature waves progressing as pulsatile fronts are detected at appropriate parameter values.
