A bipolar junction transistor (BJT) is a type of transistor in which both electrons and electron holes serve as charge carriers. In contrast, a unipolar…

Metamaterial antennas are a type of antenna that uses metamaterials to improve the performance of miniature (electrically small) antenna systems. Their function, like that of…

Linear elasticity is a key topic in solid mechanics, specifically the study of materials’ mechanical behavior. It is a mathematical model that describes how solid…

An electromagnetic clutch is a form of clutch that uses electromagnetic force to engage and disengage the machine’s driving and driven components. This type of…

An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor that functions primarily as an electronic switch. It is a semiconductor device that is widely…

A crossatron is a high-power pulsed modulator device made up of a cold cathode gas-filled tube that incorporates features from thyratrons, vacuum tubes, and power…

Arcing horns (also known as arc-horns) are projecting conductors that shield insulators or switch hardware in high-voltage electric power transmission lines from damage during a…

Historically, assessments of how climate change will affect global economy have been based on annual temperature fluctuations. However, the extra effects of variability and extremes…

Discrimination may accelerate the biological processes of aging, according to a new study headed by academics at the NYU School of Global Public Health. The…

Electric power quality refers to how closely a power supply system’s voltage, frequency, and waveform adhere to defined criteria. A stable supply voltage that remains…

Concentrated Solar Power (CSP) is a method that employs mirrors or lenses to focus a great amount of sunlight on a small area. This focused…

Metamaterial cloaking uses artificial materials known as metamaterials to modify the behavior of light or other electromagnetic waves. These materials are engineered to have unique…
