隧道效应是波的一般特性

The Tunnel Effect Should Be Considered asthe Universal Nature of All Waves

该文以光波和声波为例,表明了在介质中存在的迅衰场是波发生全反射的必要条件,导出了波穿透势垒的透射率的一般表达式．指出隧道效应与波的干涉和衍射一样,也是各种波动都具有的共同特性．

Abstract: Taking the light and sound waves as the examples, we show that the evanescent field is the nacessary condition of occurence of the total reflection, the general mathematical expression of the transmissivity is deduced for various waves. We suggest that the tunnel effect should be considered as an universal nature of all waves,like the diffraction,the interference and so on.
