✦ Synopsis

We reconstruct a two-dimensional obstacle D from knowledge of its Dirichletto-Neumann map on the boundary of a domain enclosing D. To do so, we first prove existence and uniqueness of exponentially growing solutions to an exterior problem which is of independent interest.

## Abstract This paper develops a 2D time domain boundary element method (BEM) to solve the transient SH‐wave scattering from an inclusion with a unilateral frictional interface. The incident SH‐wave is assumed strong enough to break friction so that localized slip takes place along the interface.
