隨著高速信號時代的來臨，訊號傳輸的速度變得越來越快，電磁干擾所產生的問題變得越來越重要，為了進行準確的電磁量測，人們相繼開發不同量測環境，其中混響室是最常用來進行有關電磁相容的量測之一。
然而，建造大型的量測環境的成本要價不斐，為了能便宜且快速地進行電磁量測，本實驗室建造了一個小型混響室來進行實驗，為驗證該混響室所量測參數的準確性，我們使用商業模擬軟體對待測物進行了全波模擬，以及使用了大型的電磁環境進行量測來進行對比。
本論文將從介紹各種不同的電磁量測環境，以及混響室內的各種不同電波理論，也會詳細地構述我們混響室的建造過程以及量測各參數的理論與實驗步驟。

With the advent of the high-speed signal era, the speed of signal transmission has become increasingly faster, and the issues caused by electromagnetic interference have become more significant. To conduct accurate electromagnetic measurements, various measurement environments have been developed, with reverberation chambers being one of the most commonly used for electromagnetic compatibility (EMC) testing.
However, constructing large measurement environments can be extremely costly. To achieve affordable and efficient electromagnetic measurements, our laboratory built a small reverberation chamber for experiments. To verify the accuracy of the parameters measured in this chamber, we conducted full-wave simulations on the device under test using commercial simulation software, and we also performed measurements in a large electromagnetic environment for comparison.
This thesis will introduce various electromagnetic measurement environments, along with different wave theories applicable to reverberation chambers. It will also detail the construction process of our reverberation chamber and the theoretical and experimental procedures for measuring various parameters.
