Recovery of Small Inhomogeneities from the Scattering Amplitude at a Fixed Frequency
نویسندگان
چکیده
We derive rigorously the leading order term in the asymptotic expansion of the scattering amplitude of a collection of a finite number of dielectric inhomogeneities of small diameter. We then apply this formula for the purpose of identifying the location and certain properties of the shapes of the inhomogeneities using measurements of the scattering amplitude at a fixed frequency. Joint work with: Habib Ammari, Ekaterina Lakovleva and Shari Moskow

Recovery of Inhomogeneities and Buried Obstacles
In this paper we consider the unique determination of inhomogeneities together with possible buried obstacles by scattering measurements. Under the assumption that the buried obstacles have only planar contacts with the inhomogeneities, we prove that one can recover both of them by knowing the associated scattering amplitude at a fixed energy.
متن کاملAn Inverse Problem for Point Inhomogeneities
We study quantum scattering theory off n point inhomogeneities (n ∈ N) in three dimensions. The inhomogeneities (or generalized point interactions) positioned at {ξ1, . . . , ξn} ⊂ R3 are modeled in terms of the n2 (real) parameter family of self-adjoint extensions of−∆ ∣∣ C∞ 0 (R3\{ξ1,...,ξn}) in L2(R3). The Green’s function, the scattering solutions and the scattering amplitude for this model...
متن کاملSensitivity studies for imaging a spherical object embedded in a spherically symmetric, two-layer turbid medium with photon-density waves.
We present analytic expressions for the amplitude and phase of photon-density waves in strongly scattering, spherically symmetric, two-layer media containing a spherical object. This layered structure is a crude model of multilayered tissues whose absorption and scattering coefficients lie within a range reported in the literature for most tissue types. The embedded object simulates a pathology...
متن کاملThe Leading-Order Term in the Asymptotic Expansion of the Scattering Amplitude of a Collection of Finite Number of Dielectric Inhomogeneities of Small Diameter
We rigorously derive the leading-order term in the asymptotic expansion of the scattering amplitude for a collection of a finite number of dielectric inhomogeneities of small diameter. The asymptotic formula derived in this paper provides the basis for the numerical reconstruction of dielectric scatterers of small diameter, as demonstrated by Volkov.

متن کاملNonlinear Dynamic Analysis of Cracked Micro-Beams Below and at the Onset of Dynamic Pull-In Instability
In this paper, the effect of the crack on dynamic behavior of cracked micro-beam in the presence of DC and AC loads are investigated. By applying the residual axial stress and fringing field stress, a nonlinear analytical model of cracked micro-beam is presented and crack is modeled by a massless rotational spring. The governing equation of the system is solved using Galerkin procedure and shoo...
