In our previous session we reviewed the most common passive elements used in electronic circuits. This time we look at semiconductors, and at some of the important active elements made from them: ...

The first commuter aircraft, powered by super-efficient hybrid-electric propulsion systems, could be taking their first paying passengers sometime in 2027. Part 3 provides an engineer’s-eye ...

This lab course introduces students to modern topics of engineering optics. Teams of students will carry out four different projects: holography, lasers, free-space optical communication, and ...

Powered by a combination of batteries and internal combustion, hybrid-electric aircraft can cut CO 2 emissions by 50% or more along with offering dramatically lower operating costs. While the low ...
