For the first time, engineers have built a cement composite that doesn't just resist cracking, it forces cracks to take the ...

MIT researchers have built a nanoscale photonic device shaped like a tiny ski jump that launches laser light directly off a ...

The impact that faster and more powerful laser cutting machines have had on the typical metal fabricating shop floor is undeniable. Just ask the bending department. It wasn’t too long ago that one ...

Abstract: Accurate characterization of surfaces using cantilever-based optical beam deflection (OBD) systems is crucial for obtaining the sample’s “true” topography and its corresponding material ...

Abstract: The metasurface can provide beam deflection by providing phase gradient. In this work, a single-layer small size transmission-type metasurface is used to generate a deflect beam in the ...
