Researchers from New York University have designed a configuration of coils for a stellarator, a type of device that controls fusion reactions. The shape, number and position of the coils are ...

Coupling is the transfer of energy which happens in the space between the heating portion of the coil and the workpiece. Thus, coupling distance is how big a space must be to balance manufacturing ...

An RF signal can be radiated effectively if the linear dimension of the antenna is comparable with the wavelength of the operating frequency. In an RFID application utilizing the VLF (100 kHz – 500 ...

For decades, the fusion reactor design known as a stellarator has had a specific, documented, expensive problem: designing the magnetic coils that make it work. The coils must simultaneously satisfy a ...

How efficiently and effectively a workpiece is heated is determined by the design and type of the induction coil. Work coils range in complexity from a simple solenoid- or helical-wound coil (made up ...
