abstract = {<p style="text-align: justify;">Considering the acoustic source scattering problems, when the source is non-radiating/invisible, we investigate the geometrical characterization
for the underlying sources at polyhedral and conical corner. It is revealed that
the non-radiating source with Hölder continuous regularity must vanish at
the corner. Using this kind of geometrical characterization of non-radiating
sources, we establish local and global unique determination for a source with
the polyhedral or corona shape support by a single far field measurement.
Uniqueness by a single far field measurement constitutes of a long standing
problem in inverse scattering problems.</p>},
