The Interior Inverse Electromagnetic Scattering for an Inhomogeneous Cavity
Fang Zeng, Shixu Meng
In this paper we consider the inverse electromagnetic scattering for a cavity surrounded by an inhomogeneous medium in three dimensions. The measurements are scattered wave fields…
On the spectral asymptotics of waves in periodic media with Dirichlet or Neumann exclusions
Othman Oudghiri-Idrissi, Bojan B. Guzina, Shixu Meng
We consider homogenization of the scalar wave equation in periodic media at finite wavenumbers and frequencies, with the focus on continua characterized by: (a) arbitrary Bravais l…
A convergent low-wavenumber, high-frequency homogenization of the wave equation in periodic media with a source term
Shixu Meng, Othman Oudghiri-Idrissi, Bojan B. Guzina
We pursue a low-wavenumber, second-order homogenized solution of the time-harmonic wave equation at both low and high frequency in periodic media with a source term whose frequency…
Factorization method versus migration imaging in a waveguide
Liliana Borcea, Shixu Meng
We present a comparative study of two qualitative imaging methods in an acoustic waveguide with sound hard walls. The waveguide terminates at one end and contains unknown obstacles…
A rational framework for dynamic homogenization at finite wavelengths and frequencies
Bojan Guzina, Shixu Meng, Othman Oudghiri-Idrissi
In this study, we establish an inclusive paradigm for the homogenization of scalar wave motion in periodic media (with or without the source term) at finite frequencies and wavelen…
Leading and second order homogenization of an elastic scattering problem for highly oscillating anisotropic medium
Yi-Hsuan Lin, Shixu Meng
We consider the scattering of elastic waves by highly oscillating anisotropic periodic media with bounded support. Applying the two-scale homogenization, we first obtain a constant…
