一、微波测量问题微波测量向计量工作者提出一系列独特的问题。由于微波元件的尺寸与电磁波的波长可相比拟,一般说来,元件对电磁波的延迟效应是不能忽略的。因此,在早期人们认为电磁场理论是描述和计算微波系统的适用工具。然而不久,人们认识了单导体波导中波的传播同熟知的 TEM(横电磁波)同轴线中波的传播有一定的相似性。这种认识迅速
First, the microwave measurement issues Microwave measurement to the measurement workers put forward a series of unique problems. Since the size of the microwave component can be compared with the wavelength of the electromagnetic wave, in general, the delay effect of the component on the electromagnetic wave can not be neglected. Therefore, in the early days people think that the electromagnetic field theory is a suitable tool to describe and calculate the microwave system. However, it was not long before people realized that the propagation of waves in single-conductor waveguides has some similarity to the propagation of waves in well-known TEM (transverse electromagnetic waves) coaxial lines. This awareness is rapid
