Abstract
Boundaries between domains of traveling waves are studied in convectio n in an 8% mixture of ethanol and water. A configuration is described in which rolls move in opposite directions on either side of a domain wall. Demodulation techniques are used to measure the interaction of w aves across the boundary. It is found that rolls approaching the bound ary with an oblique angle of incidence are reflected from the boundary . The reflection coefficient and the attenuation of the reflected wave are measured.
