The design of magnetic resonance imaging (MRI) gradient coils is a critical element in optimising image quality and system performance. These coils generate spatially varying magnetic fields, which ...

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 ...

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 ...

A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor. The name “voice coil” comes from one of its historically first applications: vibrating ...
