Title:
磁気検出装置及び磁気検出方法
Document Type and Number:
Japanese Patent JP7380392
Kind Code:
B2
Abstract:
A magnetism detection device (1; 101) comprises: a transmission line set (2; 102) comprising a transmission line (20; 120A, 120B; 220; 320; 420; 520; 620; 720), the transmission line (20; 120A, 120B; 220; 320; 420; 520; 620; 720) comprising at least one first conductor (21; 221; 321; 421; 521; 621; 721), the at least one first conductor (21; 221; 321; 421; 521; 621; 721) being linear and comprising a magnetic material; and a detector (30; 130) configured to: input, from a first end of the transmission line set (2; 102), a pulse signal as a first incident wave; detect, at the first end, a first reflected wave of the first incident wave; input, from a second end opposite to the first end, a pulse signal as a second incident wave; detect, at the second end, a second reflected wave of the second incident wave; and detect a strength of a magnetic field applied to the transmission line set (2; 102) based on compositing of the first reflected wave and the second reflected wave.
