Metamaterials are artificial composite materials engineered to have properties that may not
be found in nature. By exploring locally resonant effect of the building units, elastic …

In this work, a broadband and broad-angle polarization-independent random coding
metasurface structure is proposed for radar cross section (RCS) reduction. An efficient …

We propose and demonstrate efficiently molding surface plasmon polaritons (SPPs) based
on transformation optics. SPPs are surface modes of electromagnetic waves tightly bound at …

Plasmon resonances and extraordinary light scatterings of a nanoparticle with radial
anisotropy are studied and summarized. The coupling between localized surface plasmons …

We present a practical design of an underwater acoustic carpet cloak with 2-dimensional
version of the pentamode lattice. The quasi-conformal transformation, which is achieved by …

Recently, there are emerging demands for isotropic material parameters, arising from the
broadband requirement of the functional devices. Since inverse Laplace's equation with …

The aim of this review is to give an overview of techniques and methods used in the
modeling of acoustic and elastic metamaterials. Acoustic and elastic metamaterials are man …

Millimeter-wave backscatter can simultaneously support high-precision sensing and
massive communication and represent one prominent technical evolution in next-generation …

A lattice design of a cloak for full two-dimensional elasticity is suggested when the
background continuum is isotropic with Lamé parameters (λ, μ) satisfying μ≤ λ. The lattice is …

We develop an optimization framework for the design of acoustic cloaks, with the aim of
overcoming the limitations of usual transformation-based cloaks in terms of microstructure …
