Huruf ini membentangkan ciri-ciri keseragaman medan bagi ruang gema prisma segi tiga. Ruang gema yang biasanya menggunakan pengacau untuk mencipta medan elektrik seragam di dalamnya adalah alternatif kepada ruang separa anechoic untuk ujian keserasian elektromagnet. Untuk mengatasi masalah saiz dan penyelenggaraan pengacau, kami mencadangkan untuk menggantikannya dengan Peresap Residu Kuadratik yang biasa digunakan dalam akustik. Untuk mengesahkan bahawa penyebar adalah alternatif yang sah kepada pengacau, peresap dan ruang gema prisma segi tiga sama sisi direka dan direka untuk operasi 2.3-3.0 GHz. Untuk menyiasat ciri-ciri keseragaman medan dengan mempelbagaikan lokasi antena pemancar, kedua-dua simulasi dan pengukuran dalam ruang gema prisma segi tiga juga dilakukan pada dua kedudukannya, masing-masing. Program komersial XFDTD 6.2, yang melibatkan domain masa perbezaan terhingga (FDTD), digunakan untuk simulasi dan taburan kebarangkalian terkumpul, yang disyorkan oleh IEC 61000-4-21, digunakan untuk menilai keseragaman medan. Kedua-dua hasil simulasi dan pengukuran menunjukkan bahawa keseragaman medan dalam ruang memenuhi keperluan piawaian antarabangsa

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
