摘　　要：针对电磁兼容测试中对磁场探测的需要,提出一种新型的集成光学磁场探测器,它的探测头是由LiNbO3光波导调制器和双负载环天线构成的。由于电磁感应和电光效应,通过探测输出光强便可得知磁场的相关信息。与传统的磁场探测器相比,它具有体积小,对被测场干扰小的特点,并且能够有效抑制电场的影响,提高了探测准确性。通过设计探测头,得到了满足探测要求的光波导磁场探测器,并对该结构进行了仿真,仿真结果与此前的分析吻合,证实了探测器的设计是合理的。A new type of integrated optical waveguide magnetic field probe was proposed for electromagnetic compatibility test. The probe head is constituted with a LiNbO3 optical waveguide modulator and a doubly-loaded loop antenna element. The magnetic field information can be obtained by detecting the output optical intensity. Compared with the traditional magnetic field probes, it has lower disturbance of measured field, and can suppress the electrical influence effectively. Simulation result is consistent with the theoretical analysis.
