摘要：We present a rather simple proof of the existence of resonant
frequencies for the direct scattering problem associated to a
system of elastic wave equations with Dirichlet boundary
condition. Our approach follows techniques similar to those in
Cortés-Vega (2003). The proposed technique relies on a
stationary approach of resonant frequencies, that is, the poles of
the analytic continuation of the solution.
