Abstract
The magnetic detector 1 according to the present disclosure includes a transmission line 10 having a linear first conductor 11 including a magnetic material, a signal generator 30 configured to input a pulse as an incident wave to the transmission line 10, and a calculator 20 configured to detect a reflected wave caused by impedance mismatching at a magnetic field application position of the transmission line 10 and the incident wave. The calculator 20 calculates a position and a strength of the magnetic field applied to the transmission line 10 on the basis of the incident wave and the reflected wave.
Claims14
A magnetic detector, comprising:
- a transmission line having a linear first conductor including a magnetic material;
- a signal generator configured to input a pulse as an incident wave to the transmission line;
- and
- a calculator configured to detect a reflected wave generated at a magnetic field application position of the transmission line due to impedance mismatching and the incident wave, wherein
- the calculator calculates a position and a strength of a magnetic field applied to the transmission line based on the incident wave and the reflected wave.
A magnetic detection method in a magnetic detector comprising a transmission line having a linear first conductor including a magnetic material, a signal generator and a calculator, the magnetic detection method comprising:
- inputting, by the signal generator, a pulse as an incident wave to the transmission line;
- detecting, by the calculator, a reflected wave caused due to impedance mismatching at a magnetic field application position of the transmission line and the incident wave;
- and
- calculating, by the calculator, a position and a strength of a magnetic field applied to the transmission line based on the incident wave and the reflected wave.
