Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...

From skyscrapers to massive bridges, I-beams help engineers build stronger structures with less material. Their distinctive shape is designed to handle bending loads as efficiently as possible.

The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one ...

The quality of light in an LED luminaire depends on both the source and on how the light is distributed. Image Credit: nikkytok/Shutterstock.com LED diffusers are optical components that scatter, ...

YouTuber [MechnicalRedPanda] has recreated a DIY STM hack we covered about ten years ago, updating it to be primarily 3D-printed, using modern electronics, making it much more accessible to many folks ...

Abstract: A dual-circularly polarized (D-CP) low-profile folded reflectarray (FRA) capable of simultaneous two-dimensional (2-D) beam scanning is proposed. The FRA consists of a planar feed embedded ...

Abstract: To address complex optimization challenges in engineering, such as the welded beam design (WBD) problem, this research work introduces the Artificial Gorilla Troops Optimizer (GTO), an ...
