摘要
We consider waves travelling in two different mediums each endowed with a different constant speed of propagation. At the interface between the two mediums, the refraction of the rays of the optic geometry obeys the Snell's law. We provide sufficient conditions on the geometry' of the mediums and on the speed of propagation for the exact boundary controllability.
