Electromagnetic metastructures stand for the artificial structures with a characteristic size
smaller than the wavelength, which may efficiently manipulate the states of light. However …

Metamaterials are the major type of artificially engineered materials which exhibit naturally
unobtainable properties according to how their microarchitectures are engineered. Owing to …

A switchable bi-functional optical metamaterial for broadband absorption and broadband
cross-polarization conversion is proposed in the terahertz band based on the phase …

A simple multiband metamaterial-loaded monopole antenna suitable for wireless local area
network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications …

Lightweight, and broad and strong absorption are still a huge challenge for electromagnetic
(EM) wave absorbers. Here, we propose a facile oxidative polymerization-carbonization …

A compact tri-band planar monopole antenna is proposed that employs reactive loading and
a¿ defected¿ ground-plane structure. The reactive loading of the monopole is inspired by …

Novel circular polarized sensors and antennas for biomedical systems, energy harvesting,
Internet of Things (IoT), and 5G devices are presented in this article. The major challenge in …

This paper presents the design and analysis of compact coplanar waveguide (CPW)-fed
zeroth-order resonant (ZOR) antennas. They are designed on a CPW single layer where …

Miniaturized waveguide slot antennas using negative order resonance are proposed and
developed in this paper. The design of these novel resonant-type antennas is based on the …

Vanadium dioxide (VO 2) has been widely used in tunable terahertz (THz) metamaterial
absorbers. So far, many kinds of tunable broadband or dual-broadband THz metamaterial …
