Acoustic metamateiral (AM) is an artificially structured material with the unique properties that cannot be found in nature materials, such as negative refraction, slab focusing, super-resolution imaging, cloaking, inverse Doppler effect, etc. In thi

It is always an issue for researchers to control the propagation of sound wave at will. A kind of acoustic metamaterial built with artificial microunits attracts the attention of researchers, because it possesses many unique properties that cannot be

We propose an isotropic structure based on double split-ring resonator. We investigate experimentally and numerically the electromagnetic resonant properties of the proposed structure. The result shows that when the electromagnetic wave transmits in

We present a new kind of zero-index metamaterial composed of periodic array of dendritic cells with continuous long pole, and investigate its electromagnetic characteristics. First, we study the one-level dendritic cell with continuous long pole. The

In this paper, we design a three-dimensional isotropic left-handed metamaterial (LHM) composed of sphere-thorn shaped cells at visible frequencies. Adopting the metallic Drude's principle, we simulate and study its transmission properties for the inc

We experimentally studied the tunable effects of connective dendritic left-handed metamaterials based on electrorheological fluids. Three influencing factors-the distance of electrodes,the permittivity of embedding media,and the intensity of appl

We fabricated a kind of 1D metamaterial which consists of periodic array of Helmholtz resonators and tested its acoustic transmission at audible sound frequency in air. The experimental results show that a transmission dip appears at the frequency ra
