WebWe impose the well-known Sommerfeld radiation boundary condition upon the scattering wave: usc:=u −uin (where uin is a given incident wave): ∂rusc −ik usc =o(r−1/2) as r →∞, (1.5) where i = √ −1 is the complex unit. The challenges of the above problem are at least threefold: (i) unboundedness of the computational domain; WebA possible definition of the term “open boundary” is suggested in order to limit the discussion. Some popular and recently suggested conditions are reviewed and discussed. Emphasis is on conditions based on the Sommerfeld radiation condition including the Orlanski type and modifications thereof, but also sponges are considered.
