## Abstract We consider acoustic scattering problems described by the mixed boundary value problem for the scalar Helmholtz equation in the exterior of a 2D bounded domain or in the exterior of a crack. The boundary of the domain is assumed to have a finite set of corner points where the scattered

## Abstract When the field radiated by an antenna is measured in the near‐field region, this must be transformed into far‐field. If a spherical wave expansion is used for this transformation, the transmission formula must be solved, and hence the probe receiving coefficients must be known. Normally
