The Behaviour of Induction Coils in the High Frequency Range

Induction heating of aluminium billets using superconducting coils

It is proposed to apply high-temperature superconducting (HTS) tape in the coil windings for induction heaters for aluminium or copper extrusion billets. The potential for efficiency improvements is substantial, as conventional copper coil induction heaters rated for up to around 1 MW operate with an overall efficiency of typically only 50–60%. The efficiency of a HTS induction heater depends v...

Catheter Coils

Magnetic resonance imaging (MRI) is a very powerful tool for diagnostic imaging; however, it is very seldom used for guiding interventional procedures. On the other hand, in many procedures the quality of the guiding image modality is less than perfect, and therefore, MRI can be considered as an alternative. Among these interventional procedures, the percutaneous cardiovascular procedures have ...

A Missile-Borne Angular Velocity Sensor Based on Triaxial Electromagnetic Induction Coils

Aiming to solve the problem of the limited measuring range for angular motion parameters of high-speed rotating projectiles in the field of guidance and control, a self-adaptive measurement method for angular motion parameters based on the electromagnetic induction principle is proposed. First, a framework with type bent "I-shape" is used to design triaxial coils in a mutually orthogonal way. U...

Application of Magnetic Circuit and Multiple-Coils Array in Induction Heating for Improving Localized Hyperthermia

Aiming the application of localized hyperthermia, a magnetic induction system with new approaches is proposed. The techniques in this system for improving the effectiveness of localized hyperthermia are that using magnetic circuit and the multiple-coil array instead of a giant coil for generating magnetic field. Specially, amorphous metal is adopted as the material of magnetic circuit. Detail d...
