Symbol of the Dirichlet-to-Neumann operator in 2D diffraction problems with large wavenumber
Margarita F. Kondratieva, Sergey Yu. Sadov
We put forward a conjecture about an universal asymptotical behaviour of the symbol of the Dirichlet-to-Neumann operator (considered as a pseudodifferential operator) in the 2D ext…
