A Direct Sampling Method for Inverse Electromagnetic Medium Scattering
Kazufumi Ito, Bangti Jin, Jun Zou
In this paper, we study the inverse electromagnetic medium scattering problem of estimating the support and shape of medium scatterers from scattered electric or magnetic near-fiel…
A Two-stage Method for Inverse Medium Scattering
Kazufumi Ito, Bangti Jin, Jun Zou
We present a novel numerical method to the time-harmonic inverse medium scattering problem of recovering the refractive index from near-field scattered data. The approach consists…
Error estimates for a semidiscrete finite element method for fractional order parabolic equations
Bangti Jin, Raytcho Lazarov, Zhi Zhou
We consider the initial boundary value problem for the homogeneous time-fractional diffusion equation $\partial^α_t u - \De u =0$ () with initial condition a…
An inverse Sturm-Liouville problem with a fractional derivative
Bangti Jin, William Rundell
In this paper, we numerically investigate an inverse problem of recovering the potential term in a fractional Sturm-Liouville problem from one spectrum. The qualitative behaviors o…
Gradient-based estimation of Manning's friction coefficient from noisy data
Victor M. Calo, Nathan Collier, Matthias Gehre +2
We study the numerical recovery of Manning's roughness coefficient for the diffusive wave approximation of the shallow water equation. We describe a conjugate gradient method for t…
