In this book Dirichlet and Neumann boundary control problems subject to the Helmholtz equation - which has to be solved in three dimensional unbounded exterior domains - are considered. The observation takes place on volumes, two dimensional manifolds, curves or finitely many points. Boundary Integral Equations and the corresponding Boundary Element Method are used to solve the Helmholtz equation in unbounded exterior domains.
