TITLEProbe Type Method for Acoustic Wave Equations with Discontinuous Coefficients

ABSTRACT By adapting the idea of Belishev given in the paper below, we will show how the boundary control method abbreviated by BC method can be used to identify an unknown inclusion inside the medium. This idea is quite similar to the probing type argument for the Helmholtz equation and heat equation.
