Scattering by obstacles and wave problem of minimal resistance
We consider the wave analogue of the classical Newton problem of
the body of minimal resistance. In the wave setting, instead of a
homogenuous parallel flow of particles and classical resistance,
one should consider a plane wave and the transport cross section.
Trying to solve the problem, we found some new natural effects of
scattering theory unknown even for physicists.
