| Abstract: | Waves in a perfectly conducting elastic medium are considered in two cases: 1) at the free surface of a medium occupying an infinite halfspace and located in a homogeneous constant magnetic field; 2) at the interface of two media one of which is located in a magnetic field. At a certain relative velocity instability develops. A similar problem was investigated in [1] for zero magnetic field and a critical velocity was obtained. This paper examines the instability due to vibrations propagating at right angles to the magnetic field.The author thanks M. I. Kiselev for his helpful suggestions. |
