On the surface Bloch waves in truncated periodic media: scalar-wave primer
Bojan B. Guzina, Shixu Meng, Prasanna Salasiya +1
Much like their counterparts in homogenous elastic solids, waves in periodic media can be broadly classified into Floquet-Bloch body waves, and evanescent surface waves. Our goal i…

On the recovery of two function-valued coefficients in the Helmholtz equation for inverse scattering problems via inverse Born series
Fioralba Cakoni, Shixu Meng, Zehui Zhou
In this work, we construct the Born and inverse Born approximation and series to recover two function-valued coefficients in the Helmholtz equation for inverse scattering problems…
