Factorization method for inverse time-harmonic elastic scattering with a single plane wave

<p style='text-indent:20px;'>This paper is concerned with the factorization method a single far-field pattern to recover an arbitrary convex polygonal scatterer/source in linear elasticity. The approach also applies compressional (resp. shear) part of excited by plane wave. one-wave based on scattering data for priori given testing scatterers. It can be regarded as domain-defined sampling and does not require forward solvers. We derive spectral system operator rigid disks show that, using disks, justified independently classical method.</p>
