Abstract: This letter proposes a sandwich metamaterial window (SMW) for a W-band TE01 mode gyrotron travelling-wave tube (gyro-TWT), which is optimized using machine learning (ML) to achieve high ...

Abstract: A tunable 2-bit encoder, switch, and absorber using a graphene-based terahertz (THz) metamaterial were developed to operate within 1-4 THz range. The metamaterial comprises three resonators ...

Metamaterials are composites with a very precisely controlled structure. It is this structure that determines the properties of the metamaterial, not the substances it is made of. Typically, a ...

Neurophos, a startup company based in Austin, Texas, that is working on photonic chips based around metamaterial optical modulators, says it raised $110 million in a series A round of venture funding.

Thomas Allen receives funding from the Engineering and Physical Sciences Research Council (EPSRC) as a co-investigator of the UK Metamaterials Network. He worked with HEAD Sport GmbH on auxetic ...

The age of smart, self-optimizing materials has begun. A programmable metamaterial has been developed that shatters the limits of old material science. US researchers at the University of Connecticut ...

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 ...

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 ...

Ansys Inc. (Pittsburgh, Pa., U.S.) has announced that simulation product Ansys 2025 R2 features new AI-powered capabilities across the portfolio that accelerate simulation and expand accessibility. R2 ...

Imagine this: you’re in the middle of an important project, juggling deadlines, and collaborating with a team scattered across time zones. Suddenly, your computer crashes, and hours of work vanish in ...

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...
