본 논문은 전자기 간섭을 측정하기 위해 개방형 시험장이나 무향실을 대체할 수 있는 삼각 프리즘 잔향실의 전계 균일성 특성을 제시합니다. 잔향실에서 균일한 음장을 생성하는 공식 장치인 교반기의 크기 문제를 개선하기 위해 Quadratic Residue Sequence 방식의 디퓨저를 제안합니다. 교반기를 디퓨저로 대체하는 것을 검증하기 위해 1-3GHz용 디퓨저를 설계하고 세 가지 유형의 정삼각 프리즘 잔향실을 모델링했습니다. 그 후, 이 6.2개 잔향실의 장 분포를 시뮬레이션하고 테스트합니다. 유한 차분 시간 영역 방법인 XFDTD 61000를 사용하여 각 구조의 필드 편차를 시뮬레이션하고 서로 비교합니다. 필드 균일성의 평가는 IEC 4-21-XNUMX에 지정된 누적 확률 분포를 통해 수행됩니다. 결과는 챔버의 필드 균일성이 다음 범위 내에 있음을 보여줍니다.

Abstract: This paper presents the field uniformity characteristics in a triangular prism reverberation chamber that can be substituted for an open area test site or an anechoic chamber to measure electromagnetic interference. To improve size problems of a stirrer that is an official unit to generate a uniform field in the reverberation chamber, we suggest a diffuser of Quadratic Residue Sequence method. To validate the substitution of a diffuser for a stirrer, a diffuser is designed for 1-3 GHz, and three types of equilateral triangular prism reverberation chambers are modeled. Afterwards, the field distributions in these three reverberation chambers are both simulated and tested. Using XFDTD 6.2 of finite difference time domain method, field deviations of each structure are simulated and compared to each other. An evaluation of field uniformity is done by cumulative probability distribution which is specified in the IEC 61000-4-21. The result shows that the field uniformity in the chamber is within
