Abstract: This communication presents a liquid crystal (LC)-based electronically tunable metamaterial unit cell that can serve as a building block for dynamic metasurface antennas (DMAs). The ...

Researchers have developed a design principle enabling the creation of complex patterns on silicon chips by way of microfabrication. Thanks to these patterns, vibrations follow predetermined paths. A ...

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 ...

Why are Metamaterials Unlike Anything in Nature? Material properties are typically defined by electric permittivity (ε) and magnetic permeability (μ), with free space representing the baseline values ...

Controlling low-frequency broadband sound using compact structures remains a core challenge in acoustics. Achieving efficient, wideband sound absorption with lightweight, thin materials is vital for ...

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 ...

ANSYS, Inc.’s ANSS Lumerical Photonic Design Tools have been certified by GlobalFoundries for use on the GF Fotonix platform. This is set to empower engineers with high-fidelity simulation ...
