dc.description.abstract본 논문에서는 CRD(Cubical Residue Diffuser)를 이용하여 전자파 잔향실 내의 전기장 균일도를 향상시키고, 잔향실 내의 전기장 균일도가 최적화되는 CRD 면적비를 연구하였다. 1 ~ 3 ㎓ 주파수 대역에서 Schroeder 방식의 CRD를 설계하였고, 전자파 잔향실 내의 전기장 분포 해석을 위해 FDTD(Finite Difference Time Domain) 수치해석이 이루어졌다. 해석결과 2 ㎓에서 CRD의 면적이 잔향실 한쪽 내벽의 약 40 ~ 80 %일 경우 전기장 강도 표준 편차가 낮고 균일하게 분포되었으며, 40 % 이하, 또는 80 % 이상의 면적에서는 표준 편차가 높게 나타났다. 특히 가장 나쁜 경우와 비교하여 44%일 때 전기장 균일도가 1 ㏈ 향상됨을 알 수 있었다. This paper presents an improved field uniformity in a reverberation chamber, that can be alternatively used for the analysis and the measurement of electromagnetic interference and immunity, with a designed CRD(Cubical Residue Diffuser) that have various dimensions. The Schroeder type CRD is designed for 1 ~ 3 ㎓ band and the FDTD(Finite Difference Time Domain) method is used to analyze the field characteristics. At 2 ㎓, the standard deviation of test volume in the reverberation chamber is the smallest and has a good field distribution with a CRD of 40 ~ 80 % dimension of one side of the reverberation chamber. The Electric field uniformity gets worse when the dimension of a CRD is either below 40 % or above 80 % of the side wall. The result shows that the standard deviation of the test volume in the reverberation chamber with a CRD of 44 % dimension is improved by 1 ㏈ compared with that of the reverberation chamber with a CRD of 100 % dimension.en_US
