Abstract

Abstract

The connecting face of small loop probe is optimized with slope cutting, so that the probe can exactly measure weak coupling electromagnetic field in the cavities. Under the irradiation of electromagnetic pulse, the change of voltage in loop probe is simulated by FDTD. The receiving characteristics of three loop probes with different slopes are calculated. The high frequency receiving capability of loop probe with 15° slope is improved by 2~5 dB. The receiving experiments of 40 mm diameter loop probe with 15° slope are conducted. Measurement result is compared with calculation result, whose change trends coincide well in the main, which proves credibility of numerical analysis．
