概述究竟什么是微波?这是我们关心的首要问题。从现象看,如果把电磁波按波长(或频率)划分,则大致可以把300MHz～3000GHz,(对应空气中波长λ是1m～0.1mm)这一频段的电磁波称之为微波。纵观“左邻右舍”它处于超短波和红外光波之间。微波的“左邻”是超短波和短波,可以扩展通讯通道;而它的“右舍”又是红外光波,与光波比较,微波穿透能力强,不受雨雾风沙等恶劣天气影响,能够更稳定可靠的工作。在这一波段中电与磁的相互转
Overview What is microwave? This is our primary concern. From the point of view of phenomena, if electromagnetic waves are divided by wavelength (or frequency), electromagnetic waves in the frequency band of 300 MHz to 3000 GHz (corresponding to a wavelength λ in the air of 1 m to 0.1 mm) can be roughly called microwaves. Throughout “neighbors ” It is between the ultra-short wave and infrared light waves. Microwave “left neighbor ” is ultra-shortwave and shortwave, can expand the communication channel; and its “right homes ” is infrared lightwave, compared with lightwave, microwave penetrating ability, not affected by bad weather such as rain, fog and sand , To be more stable and reliable work. In this band of electricity and magnetic mutual transfer
