在matlab下编程，实现对不同生硬的识别，效果非常好，能识别差别很小的不同声音。(At under matlab programming, implementation of different identification blunt, very good results to identify small differences in different voices.)

The plots of the Poynting vector might serve to show which part of the wire is mainly responsible for creating the radiated field. The movie of the modulus, |S|, does not give a clear answer, since at close distances the pointing vector reaches high values along the entire wire. The fact that |S| is high along the entire line just means that energy is shifted between the endpoints and the middle region (electric and magnetic field respectively).
