Mechanical Engineering

Engineering discipline Mechanical engineering is the study of physical machines and mechanisms that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, design, structural analysis, and electricity.

Exploring foci of: Optica • Vol 9 • No 9 Optical encryption in spatial frequencies of light fields with metasurfaces 2022 Optical encryption has attracted attention recently as information security becomes important in modern society. For most encryption methods based on metasurfaces, however, information is encrypted into the metasurfaces of physical forms, limiting information sharing and compatibility with digital information processing technology. Here, we demonstrate an alternative scheme in which information is encrypted on optical images other than metasurfaces, releasing the constraints mentioned above. This is achieved by mo… Open Article Page
