Acoustic asymmetric transmission based on time-dependent dynamical scattering
An acoustic asymmetric transmission device exhibiting unidirectional transmission property for acoustic waves is extremely desirable in many practical scenarios. Such a unique property may be realized in various configurations utilizing acoustic Zeeman effects in moving media as well as frequency-conversion in passive nonlinear acoustic systems and in active acoustic systems. Here we demonstrat...
متن کاملFirst-principles model of time-dependent variations in transmission through a fluctuating scattering environment.
Fading is the time-dependent variation in transmitted signal strength through a complex medium due to interference or temporally evolving multipath scattering. In this paper we use random matrix theory (RMT) to establish a first-principles model for fading, including both universal and nonuniversal effects. This model provides a more general understanding of the most common statistical models (...
متن کاملTime-dependent Scattering Theory for Schrödinger Operators on Scattering Manifolds *
We construct a time-dependent scattering theory for Schrödinger operators on a manifold M with asymptotically conic structure. We use the two-space scattering theory formalism, and a reference operator on a space of the form R×∂M , where ∂M is the boundary of M at infinity. We prove the existence and the completeness of the wave operators, and show that our scattering matrix is equivalent to th...
متن کاملNonreflecting Boundary Conditions for Time-Dependent Scattering
of the ordinary differential equation which occurs in the boundary condition. An exact nonreflecting boundary condition was derived previously for use with the time dependent wave equation in three Finally, we shall solve a sequence of scattering problems space dimensions. Here it is shown how to combine that boundary by using an explicit finite difference method and our condition with finite d...
متن کاملTime { Dependent Scattering Theoryof N { Body Quantum
We give a full and selfcontained account of the basic results in N{body scattering theory which emerged over the last ten years: The existence and completeness of scattering states for potentials decreasing like r ? , > p 3 ? 1. Our approach is a synthesis of earlier work and of new ideas. Global conditions on the potentials are imposed only to deene the dynamics. Asymptotic completeness is der...
