Title:
MAGNETIC PERMEABILITY MEASUREMENT PROBE AND MAGNETIC PERMEABILITY MEASUREMENT DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/228930
Kind Code:
A1
Abstract:
Provided is a magnetic permeability measurement probe capable of accurately measuring the magnetic permeability, in particular the imaginary part of a complex permeability, of a magnetic material. The probe for measuring the magnetic permeability of a magnetic material comprises: a band-shaped strip conductor formed on the front surface of a dielectric substrate; a transmission line body having a grounding conductor formed on the front surface or the back surface of the dielectric substrate; a first connector that connects to one end of each of the strip conductor and the grounding conductor; and a second connector that connects to the other end of each of the strip conductor and the grounding conductor. The strip conductor is composed of a first length part including a portion that connects to the first connector at the one end side, a second length part including a portion that connects to the second connector at the other end, and a third length part that extends between the first length part and the second length part. The third length part has a current imbalance reducing means.
