Metamaterial-based perfect absorbers (MMPAs) are promising candidates for the practical application of perfect absorbers. MMPA is usually composed of three layers. The first layer is periodically-arranged metallic patterns, whose structure and geometrical parameters should be carefully adjusted to fulfill ...
study, we choose to use binary amplitude-shift keying (2ASK) modulation technology to encode information into the amplitude of the produced acoustic vortex beams as different sequences of “0” and “1”. At the receiving end, the transfer function of the single metamaterial-based demultiplexer c...

This paper presents a detailed review upon the most recent research efforts associated with those metamaterial-based small antennas. They are discussed and classified in several different categories such as the antennas based on dispersion engineering, metaresonators, and metamaterial loadings. Some ...
This Letter explains the design and development of a wideband circularly polarised (CP) antenna based on composite metamaterial (MTM) structures which are applicable for use in small satellite applications. The presented antenna is based on a modified co-planar waveguide feeding technique. The proposed...
We summarize the basic aspects of the recently introduced concept of "metamaterial analog computing". This concept relies on metamaterial structures that are suitably designed so as to perform mathematical operations of choice (e.g., spatial differentiation, integration, or convolution) on the transvers...
A metamaterial-based dispersion compensator includes a plurality of layers arranged in a geometric structure; wherein the plurality of layers comprise engineered metamaterials; wherein the engineered metamaterials and the geometric structure are configured to compensate dispersion across a wavelength spectrum....

We propose a simple way to enormously broaden the bandwidth of the metamaterial absorber formed by a low-conductivity square alloy patch and a dielectric layer on top of an alloy ground plane. The FWHM of the device can be up to 38.8%, which is 3.6 times larger than that of the high-co...
