We review the results of investigations for brane-induced effects on thelocal properties of quantum vacuum in background of AdS spacetime. Twogeometries are considered: a brane parallel to the AdS boundary and a braneintersecting the AdS boundary. For both these cases the contribution in thevacuum expectation value (VEV) of the energy-momentum tensor is separatedexplicitly and its behavior in various asymptotic regions of the parameters isstudied. It is shown that the influence of the gravitational field on the localproperties of the quantum vacuum is essential at distance from the brane largerthan the AdS curvature radius. In the geometry with a brane parallel to the AdSboundary the VEV of the energy-momentum tensor is considered for scalar fieldwith the Robin boundary condition, for Dirac field with the bag boundarycondition and for the electromagnetic field. In the latter case two types ofboundary conditions are discussed. The first one is a generalization of theperfect conductor boundary condition and the second one corresponds to theconfining boundary condition used in QCD for gluons. For the geometry of abrane intersecting the AdS boundary, the case of a scalar field is considered.The corresponding energy-momentum tensor, apart from the diagonal components,has nonzero off-diagonal component. As a consequence of the latter, in additionto the normal component, the Casimir force acquires a component parallel to thebrane.
