Abstract: A common variant of a metasurface antenna consists of an array of metamaterial elements coupled to a waveguide feed. The guided wave excites the metamaterial elements, coupling energy from ...

Git isn't hard to learn, and when you combine Git and GitHub, you've just made the learning process significantly easier. This two-hour Git and GitHub video tutorial shows you how to get started with ...

Metamaterials are carefully engineered materials that possess desirable properties and can be used to manipulate electromagnetic, acoustic, or other types of waves in interesting ways. Some materials ...

Researchers from IMDEA Materials Institute, in collaboration with China's Nanjing and Huazhong Universities, have developed a new acoustic metamaterial capable of transmitting complex sound signals ...

Researchers at Rice University have developed a soft metamaterial that can quickly change size and shape under remote control. The team says the invention could open the door to safer, more versatile ...

A new approach to manufacturing multicolor lenses could inspire a new generation of tiny, cheap, and powerful optics for portable devices such as phones and drones. The design uses layers of ...

Metamaterials are novel composites containing structures that produce unique effects. In Zhang’s case, he structured his metamaterial with a sawtooth-patterned surface. The novel surface allows sound ...

Sound waves do far more than carry music or voices. In science and engineering, they help map the seafloor, monitor earthquakes, guide submarines, and even shatter kidney stones inside the human body.

Engineers at MIT have developed a material with a "double network" structure that makes it both stretchy and strong. Capable of stretching up to four times its default size without fully breaking, the ...

Fig. 1. The dielectric response models for conventional dielectric materials and for metamaterials. For conventional dielectric materials, there are three types of polarization models: Drude model for ...

A recent study published in Nature Communications introduces a new metamaterial, called Roliner, designed as a soft, adaptive human-machine interface for wearable devices. Roliner is made from ...

Robbie has been an avid gamer for well over 20 years. During that time, he's watched countless franchises rise and fall. He's a big RPG fan but dabbles in a little bit of everything. Writing about ...
