DESCRIPTION:In this work we study diffraction of a plane
incident wave in a complex 2D domain composed by
two \;shifted angular domains having a part of
their common boundary. The perfect (Dirichlet or
Neumann) \;boundary conditions are postulated
on the polygonal boundary of such compound domain.
By means of the \;Sommerfeld-Malyuzhinets tec
hnique the boundary-value problem at hand is reduc
ed to a \;non-standard systems of \;Malyuz
hinets-type \;functional-integral equations an
d then to a Fredholm integral equation of the seco
nd kind. Existence and uniqueness \;of the sol
ution for the diffraction problem is studied and i
s based on the Fredholm alternative for the \;
integral equation. The far field asymptotics of th
e wave field is also addressed.
