Wave field singularity aspects in large-size scatterers and inverse problems.

Wave field singularity aspects in large-size scatterers and inverse problems.

It is known that any scattered wave field carrying energy into infinity must have source singularity centers within a bounded space. Otherwise, the scattered field should be identically equal to zero everywhere (Kupradze 1935). In this paper, attention is paid to localization of these singularities...
