Finite Speed of Propagation and Local Boundary Conditions for Wave Equations with Point Interactions
We show that the boundary conditions entering in the definition of the self-adjoint operator ∆ describing the Laplacian plus a finite number of point interactions are local if and only if the corresponding wave equation φ̈ = ∆φ has finite speed of propagation.
متن کاملAnalytic solutions for the Stephen's inverse problem with local boundary conditions including Elliptic and hyperbolic equations
In this paper, two inverse problems of Stephen kind with local (Dirichlet) boundary conditions are investigated. In the first problem only a part of boundary is unknown and in the second problem, the whole of boundary is unknown. For the both of problems, at first, analytic expressions for unknown boundary are presented, then by using these analytic expressions for unknown boundaries and bounda...
متن کاملWave Equations with Point Interactions in Finite Energy Spaces
Given the abstract wave equation φ̈−∆αφ = 0, where ∆α is the Laplace operator with a point interaction of strength α, we define and study W̄α, the associated wave generator in the phase space of finite energy states. We prove the existence of the phase flow generated by W̄α, and describe its most relevant properties with particular emphasis on the associated symplectic structure and scattering the...
متن کاملAbsorbing boundary conditions for electromagnetic wave propagation
In this paper, the theoretical perfectly absorbing boundary condition on the boundary of a half{space domain is developed for the Maxwell system by considering the system in whole instead of considering each component of the electromagnetic elds individually. This boundary condition allows any wave motion generated within the domain to pass through the boundary of the domain without generating ...
متن کاملAxisymmetric Scaled Boundary Finite Element Formulation for Wave Propagation in Unbounded Layered Media
Wave propagation in unbounded layered media with a new formulation of Axisymmetric Scaled Boundary Finite Element Method (AXI-SBFEM) is derived. Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be solved by a significant reduction in required storage and computational time. The equations of the corresponding Axisymmetri...
