Consider the scattering of an electromagnetic time-harmonic plane wave by an infinite cylinder having an open crack and a bounded domain in as cross section.We assume that the enchanted taylor swift perfume crack is divided into two parts, and one of the two parts is (possibly) coated on one side by a material with surface impedance.Different boundary conditions are given on and.
Applying potential theory, the problem can be reformulated as a boundary integral system.We obtain the existence and qf1510 uniqueness of a solution to the system by using Fredholm theory.
