(Nanowerk News) Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create ...

Many mechanical structures are modeled with beam elements because they can represent any material and cross section, as well as transmit axial loads, moments, and torques. "But what if a designer must ...

Best suited for rich scattering environment. A linearly arranged and equally spaced array of antennas forms the basic structure of a beam former. In order to form a beam, each user's information ...

Scientists have used a focused beam of electrons to create some of the smallest nanowires ever made. The discovery gives a boost to efforts aimed at creating electrical circuits on mono-layered ...

Directing acoustic waves along curved paths is critical for applications such as ultrasound imaging, surgery and acoustic cloaking. Metamaterials can direct waves by spatially varying the material ...

What prompted the MIT team to research and develop a nanoscale "flashlight"? Details on the metasurface that was designed to create the source-beam collimator. How a DNN, CNN, and machine learning ...

Ever wanted to be Darth Vader? Good news: You can now bring "Star Wars" to life with an actual "tractor beam" to move small objects using sound waves, in the comfort of your own home — at least if you ...

Data from a recent integrated ground test of the Alpha high-energy laser, its beam director telescope and the associated beam alignment and correction system have provided the team developing the ...
