Direct and inverse time-harmonic elastic scattering from point-like and extended obstacles
Direct and inverse time-harmonic elastic scattering from point-like and extended obstacles
This paper is concerned with the time-harmonic direct and inverse elastic scattering by an extended rigid elastic body surrounded by a finite number of point-like obstacles. We first justify the point-interaction model for the Lamé operator within the singular perturbation approach. For a general family of pointwise-supported singular perturbations, including …
