Asymmetric calibration method on a back-to-back double-loop differential magnetic field probe
The asymmetric calibration method is a very interesting technology for differential output probes. It has been proven that the asymmetric calibration method (ACM) can broaden the application scenarios of the electromagnetic field dual probe. However, ACM is not verified on a back-to-back double-loop differential magnetic field probing system. This paper calibrates a back-to-back double-loop differential magnetic field probing system by inserting a connector for creating an asymmetry using ACM. The calibration results show that ACM can be used to calibrate an asymmetric back-to-back double-loop differential magnetic field probing system. The calibration results are further verified by measuring the standing wave magnetic field, and the verification results show that the asymmetric calibration method is effective in eliminating the asymmetry of the back-to-back double-loop differential magnetic field probing system and the work frequency band reaches up to 12 GHz.
期刊介绍：
IET Science, Measurement & Technology publishes papers in science, engineering and technology underpinning electronic and electrical engineering, nanotechnology and medical instrumentation.The emphasis of the journal is on theory, simulation methodologies and measurement techniques.
The major themes of the journal are:
- electromagnetism including electromagnetic theory, computational electromagnetics and EMC
- properties and applications of dielectric, magnetic, magneto-optic, piezoelectric materials down to the nanometre scale
- measurement and instrumentation including sensors, actuators, medical instrumentation, fundamentals of measurement including measurement standards, uncertainty, dissemination and calibration
Applications are welcome for illustrative purposes but the novelty and originality should focus on the proposed new methods.
