| Abstract: | In order to study the frequency response characteristics of segment electrodes in an integrated optical waveguide electric field sensor, they were calculated by means of finite difference time domain method, and were measured in the actual gigahertz transverse electromagnetic wave(GTEM)cell. The results show that, when the segments number is 10 and the total length of electrodes decreases from 42mm to 12mm, the responding frequency bandwidth increases from 2.68GHz to 5.91GHz; when the total length of electrodes is 42mm and the segment number increases from 10 to 30, the bandwidth of responding frequency decreases slightly from 2.68GHz to 2.51GHz. The simulated results are consistent with measurement results. |
