Abstract Thermal metamaterials are of great importance in advanced energy control and management. Previous studies mainly focused on interfaces with perfect bonding conditions. In principle, imperfectness always exists across interface and the effect

We present new exact results for the design of spherical thermal cloaks with the effect of imperfect interfaces. Thermal metamaterials are of great importance in advanced energy control and management. However, nearly all relevant studies considered

In this paper, analytic modeling for the design of a transient thermal invisibility cloak with imperfect interfaces is presented together with numerical simulations. In contrast to steady-state conditions, it is shown that an object can only be made

The subject of seismic metamaterials, inspired from novel ideas in optics and acoustics, has attracted great attention in the last decade for potential applications in earthquake engineering. Simple structure systems, like beams and plates, with peri

Metamaterials are artificially engineered and so boast properties not found in nature. One important application is in earthquake mitigation. In a 'cloaking' process, seismic metamaterials can shield buildings from seismic waves. Professor Tungyang C

We study the energy attenuation of shear horizontal waves in a half-space with an overlying layer coupled with the interaction of seismic resonators. We focus on the material anisotropic effect of the layered media, allowing that both the top layer a

We propose a simple method to design a wave trapping mechanism, referred to as an elastic open cavity, for shear horizontal waves using the concept of metasurfaces. Conventional open cavity designs have utilized bulk metamaterial media with negative

This work is to present a formulation of cloaking or concentrating device in acoustics in which the transformed material could be either having uniform bulk modulus or having homogeneous density tensor. The transformed material parameters, depending
