If you could squeeze two or three times more cellular telephone conversations into the same amount of bandwidth, how much would that be worth? To most wireless companies, the answer is, millions of ...

#OctopusEffects, #Blender Creates a laser beam from a point projected onto a surface. Create a light effect where the surface ...

Light is pushy. The physical pressure of photons is what allows for solar sail space missions that ride on sunlight, and what allows for dreams of lasers that will push those sails even faster. And ...

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 ...

(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 ...

Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make metal parts, creates large thermal gradients between areas hit by the laser and areas not being struck. This creates pools ...

crash course into Projection Mapping? His intro video laid out some of the technical groundwork of this effect, including how to use the software, and now, Shanks is back with the follow-up video. In ...

Every cat owner knows how their feline companions delight in chasing a tiny pinpoint of light from a simple laser pointer. Now, Brazilian physicists have figured out how to trap and bend laser light ...

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 ...
