摘要：
We consider wave propagation in a perturbed open waveguide. We provide a new asymptotic expansion for the scattered wave when the inclusion is of small diameter. We design a MUSIC (multiple signal classiffication) type of algorithm for locating the inclusion and illustrate its viability in numerical examples.
