SNR

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).

Newmark -β法原理Newmark-法是一种逐步积分的方法，避免了任何叠加的应用，能很好的适应非 线性的反应分析。 (Newmark-β law principle Newmark- method is a gradual integration of the ways to avoid any superposition of application, can be well adapted to nonlinear response analysis.)
