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…
A Sampling Type Method in an Electromagnetic Waveguide
Shixu Meng
We propose a sampling type method to image scatterer in an electromagnetic waveguide. The waveguide terminates at one end and the measurements are on the other end and in the far f…
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…
