Problems of acoustic and electromagnetic waves

In this thesis, the definitions of single and double layer potentials havebeen given and Dirichlet and Neumann problems have been formulatedas the Fredholm integral equations for the Laplace equation in . In single and double layer potentials for the Helmholtz equations havebeen investigated. In a nonhomogeneous medium the solution of thetime harmonic wave scattering problem has been investigated and thesolution of the acoustic wave scattering problem has been obtained. The solution of the scattering problem of the harmonic electromagnetic waves with infinite cylinder has also been obtained.
