The paper titled “Multipoint formulas for scattered far field in multidimensions” was published in “Inverse Problems” (Q1 WoS) journal. Novikov R.G. Multipoint formulas for scattered far field in multidimensions // Inverse Problems. 2020. V. 36. № 9. Article 095001. DOI:10.1088/1361-6420/aba891
The author gives, in particular, asymptotic formulas for finding the scattering amplitude at fixed frequency and angles (scattered far field) from the scattering wave function given at _n_ points in dimension _d_≥ 2. These formulas are extremely explicit and their precision is proportional to _n_. The results use, in particular, the theory of Vandermonde matrices.
