In the first chapters, the concepts of black hole and the event horizon, black hole radiation, the thermal properties of black hole, and scalar fieldradiation are introduced briefly.
The far-fieldradiation pattern of the open-end rectangular waveguide was measured and the complex coefficients of each mode were determined by this method.
这种方法先根据波导口尺寸利用惠更斯原理计算出各模式的辐射场的分布;

Based on the theoretical analysis of the near fieldradiation measurement, we designed a device for measuring its strength.
