Abstract
A magnetic detection apparatus according to the present disclosure includes a magnetic sensor and a measurement apparatus. The magnetic sensor includes a first transmission line and a second transmission line arranged to be non-parallel to each other. The measurement apparatus includes a signal generator configured to generate a first incident wave and a second incident wave, a signal detector configured to detect a first reflected wave caused by an impedance mismatch of the first transmission line and a second reflected wave caused by an impedance mismatch of the second transmission line, and a controller. The controller calculates a first magnetic field based on the first incident wave and the first reflected wave and a second magnetic field based on the second incident wave and the second reflected wave and calculates a biaxial magnetic field based on the first magnetic field and the second magnetic field.
