Designing adjustable intrinsic metamaterials with double negative electromagnetic
properties has been a challenging subject. The flexible carbon foam matrix intrinsic …

An electric inductor-capacitor (ELC) resonator provides a series of electrical resonances and
a pair of ELC resonators leads to the split of each resonance into two modes, ie, magnetic …

In this paper, a new composite metamaterial structure with negative effective mass density,
negative effective modulus, and an ultralarge Poisson's ratio is designed for vibration …

Since their revolutionary report in 1967, metamaterials have exhibited extraordinary physical
properties such as the negative refractive index and the inverse Doppler effect. In recent …

Negative permittivity is a required physical property of metamaterials which has been widely
used in some emerging and unconventional applications, such as cloaking, perfect lens and …

Negative permittivity is realized in unstructured imide polymer/carbon nanofiber (CNF)
nanocomposites. The microstructure of CNFs is one of the factors that exert profound effects …

The wave dispersion characteristics for loop array-based metamaterials were analyzed,
based on the general transmission line model of a one-dimensional host medium interacting …

A tunable dual-band acoustic metamaterial (AM) with nested two-layer split hollow spheres
(TLSHSs) is presented here, which was achieved by adjusting the hole diameter and the …

The split-ring resonator (SRR) arrays are commonly used to form a negative refractive index
metamaterial that exhibits an effective negative permeability. However, the region of …

With the development of new metamaterials made of periodic array structures, negative
permittivity has recently received more and more attention. However, it is crucial to achieve …
