이 편지는 삼각 프리즘 잔향실의 필드 균일성 특성을 나타냅니다. 일반적으로 교반기를 사용하여 내부에 균일한 전기장을 생성하는 잔향실은 전자파 적합성 테스트를 위한 반무향실의 대안입니다. 교반기의 크기 및 유지 관리 문제를 극복하기 위해 음향학에서 일반적으로 사용되는 Quadratic Residue Diffuser로 교체할 것을 제안합니다. 디퓨저가 교반기의 유효한 대안인지 확인하기 위해 디퓨저와 정삼각형 프리즘 잔향실이 2.3-3.0GHz 작동용으로 설계 및 제작되었습니다. 송신 안테나의 위치를 변경하여 전계 균일성 특성을 조사하기 위해 삼각 프리즘 잔향실의 시뮬레이션과 측정을 각각 두 위치에서 수행했습니다. 유한 차분 시간 영역(FDTD)을 사용하는 상용 프로그램 XFDTD 6.2를 시뮬레이션에 사용하고 IEC 61000-4-21에서 권장하는 누적 확률 분포를 사용하여 필드 균일성을 평가합니다. 시뮬레이션과 측정 결과 모두 챔버 내 필드 균일성이 국제 표준 요구 사항을 충족하는 것으로 나타났습니다.

Abstract: This letter presents the field uniformity characteristics of a triangular prism reverberation chamber. A reverberation chamber that generally uses a stirrer to create a uniform electric field inside is an alternative to the semi-anechoic chamber for an electromagnetic compatibility test. To overcome the size and maintenance problems of a stirrer, we propose to replace it with a Quadratic Residue Diffuser which is commonly used in acoustics. To confirm that the diffuser is a valid alternative to the stirrer, a diffuser and an equilateral triangular prism reverberation chamber are designed and fabricated for 2.3-3.0 GHz operation. To investigate the field uniformity characteristics by varying the location of the transmitting antenna, both simulation and measurement in the triangular prism reverberation chamber were also done at its two positions, respectively. A commercial program XFDTD 6.2, engaging the finite difference time domain (FDTD), is used for simulation and a cumulative probability distribution, which the IEC 61000-4-21 recommends, is used to evaluate the field uniformity. Both simulation and measurement results show that the field uniformity in the chamber satisfies the international standard requirement of
