要約(英語): This paper discussed the influence of Absorber-Lined Shielded Enclosure (ALSE) on magnetic field measurement at the frequencies of 150 kHz or lower. To evaluate the influence of the ALSE for the measurement of “Low-frequency” magnetic field, we focused on the variation value of magnetic field strength against the distance from the magnetic field source to measurement point. By applying a mirror image method to the ALSE's floor, ceiling and walls with considering their materials, we could get the calculation results that agree with three dimensional simulation results and measurement results within 3dB in the range of 0.5 m to 2.5 m, and we confirmed the influence is caused by the material characteristics of ALSE's floor, ceiling and walls. In this study, we found that the method allows to calculate the influence of ALSE easily against the low-frequency magnetic field measurement in advance.
