This paper proposes a level set-based topology optimization method for acoustic
metasurfaces consisting of multiple types of unit cells. As a type of acoustic metasurface, we …

In this paper, we propose a level set-based topology optimization method for the design of
hyperbolic acoustic metamaterials using a high-frequency homogenization method. To …

Isogeometric analysis (IGA) in the framework of the boundary element method (BEM)–
known as isogeometric boundary element analysis or IGABEM–has shown recently …

In this paper, we propose a level set-based topology optimization method for the unit-cell
design of acoustic metasurfaces by using a two-scale homogenization method. Based on …

We propose an automatic algorithm for 3D inverse electromagnetic scattering based on the
combination of topological derivatives and regularized Gauss-Newton iterations. The …

In this work we investigate the reconstruction of sound-hard obstacles buried in a bounded
material medium by a non-iterative method based on the computation of topological …

We propose a Bayesian inference framework to estimate uncertainties in inverse scattering
problems. Given the observed data, the forward model and their uncertainties, we find the …

This paper presents reconstructions of homogeneous targets from the 2D and 3D Fresnel
databases by one-step imaging methods based on the computation of topological derivative …

We present a technique to reconstruct the electromagnetic properties of a medium or a set of
objects buried inside it from boundary measurements when applying electric currents …

Purpose In this paper, the authors revisit the computation of closed-form expressions of the
topological indicator function for a one step imaging algorithm of two-and three-dimensional …
