| چکیده | ||
| محفظه طنین دارای کاربردهای گسترده ای در آنتن، مایکروویو، سازگاری الکترومغناطیسی، اندازه گیری خواص مواد و غیره است. محفظه طنین، براساس برهم زدن مدهای تحریک شده در یک محفظه بسته رسانا، توسط تعدادی همزن، عمل می کند. در این مقاله تاثیر چینش و آرایش همزنها در ایجاد تعداد مدهای مستقل که منجر به یکنواختی میدان در محفظه طنین می شود مورد بررسی قرار می گیرد. در این مقاله جهت برآورد تحلیل مناسب، برای سه حالت همزن ها(50گام، 100گام و 380 گام) در محفظه طنین RTS60، شدت میدان الکتریکی اندازه گیری شده است. تعداد مدهای مستقل در 25 نقطه فرکانسی در محدوده 250 الی 900 مگاهرتز برای سه حالت و همچنین مقادیر ضریب خودهمبستگی که بیانگر میزان استقلال مدهای تحریک شده در محفظه هست، ارائه شده است. | ||

| چکیده [English] | ||
| The reverberation chamber has wide applications in antenna, microwave, electromagnetic compatibility, measurement of material properties, etc. The reverberation chamber works based on the stirre of excited modes in a closed conductive chamber by a number of stirrers. In this paper, the influence of the arrangement of the stirrers in creating the number of independent modes that lead to the uniformity of the field in the reverberation chamber is investigated. In this paper, in order to estimate the appropriate analysis, the electric field intensity has been measured for three modes of stirrers (50 steps, 100 steps and 380 steps) in the RTS60 resonance chamber. The number of independent modes in 25 frequency points in the range of 250 to 900 MHz for three modes, as well as the values of the autocorrelation coefficient, which indicates the degree of independence of the excited modes in the chamber, are presented. | ||
