We numerically and experimentally demonstrated a metamaterial perfect absorber (MPA) in
MHz region based on a planar sandwiched metal-dielectric-metal structure. First, the single …

A frequency-selective, tunable terahertz (THz) filter based on a flexible tape is designed and
characterized for a low-cost and easy-access THz filter with a wide range of center …

In this study, we have demonstrated the fabrication of perforated absorbers on two
substrates, ie, ITO/PET and Twill weave cloth. Perforation is required to enable the use of …

The characteristics of relative permittivity and reflectance for poly (methyl
methacrylate)(PMMA) films prepared by spin-coating were investigated and an excellent …

A microwave tunable metamaterial utilizing the semiconductor-to-metal transition of
vanadium dioxide (VO2) is proposed, experimentally demonstrated and theoretically …

We present the tunability of terahertz (THz) photonic bandgaps and localization modes in
one-dimensional (1D) periodic and quasi-periodic structures based on alternating layers of …

Looking for alterable metamaterials, whose electromagnetic properties can be dynamically
and real-time controlled, has attracted a great attention recently. In this paper, we present a …

Graphene and InSb supported metamaterial structure was investigated for thermal sensing
application in the THz regime. The top metasurface comprises a squared and four …

Designing high efficiency microwave absorbers with frequencies in 1 GHz is still a huge
challenge in practical applications. We design and present a novel microwave …

There is an increasing interest for electromagnetic metamaterials that show mutable
absorption properties with real-time and dynamic control. In this paper, we investigate a …
