This paper uses the two-dimensional Brusselator model to study reflection and refraction of chemical waves.It presents some boundary conditions of chemical waves,with which occurence of observed phenomena at interface as refraction and reflection of chemical waves can be interpreted.Moreover,the angle of reflection may be calculated by using the boundary conditions.It finds that reflection and refraction of chemical waves can occur simultaneously even if plane wave goes from a medium with higher speed to a medium with lower speed,provided the incident angle is larger than the critical angle.
This paper uses the two-dimensional Brusselator model to study reflection and refraction of chemical waves. At presents some boundary conditions of chemical waves, with which occurence of observed phenomena at interface as refraction and reflection of chemical waves can be interpreted. Moreover, the angle of reflection may be calculated by using the boundary conditions. If found reflections and refraction of chemical waves can occur when even if plane wave goes from a medium with higher speed to a medium with lower speed, provided the incident angle is larger than the critical angle.
