(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 ...

Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...

Composite beams have become an integral element in modern structural engineering, combining dissimilar materials to exploit their complementary mechanical properties. This field of study encompasses ...

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 ...
