Mu Measurement Probe (muMP)
The mu measurement probe (muMP) measures complex permeability of specimens from 60 MHz to 500 MHz. It consists of a short transmission line terminated in an electrical short. Material specimens are placed or built onto a conductive back plane and the sensor is placed on top to characterize real and imaginary magnetic permeability. CEM inversion rapidly converts the measured S-parameter data into magnetic properties.
Applications of the muMP:
- This fixture characterizes materials either in a laboratory or industrial setting. The small footprint enables non-destructive testing of new materials or for quality assurance measurements of materials being manufactured. Example of how muMP has been used include:
- Characterize a variety of magneto-dielectric materials, including magnetic absorbers (e.g. magram), and low-loss magnetic substrates for miniaturized antennas.
Benefits of the muMP
- Uses CEM inversion, which combines a pre-determined lookup table with interpolation to obtain accurate magnetic properties.
- Non-destructive method that needs little or no sample preparation.
Additional Information
