由加速极化电流发射的电磁辐射携带的信息
Information carried by electromagnetic radiation launched from accelerated polarization currents
摘要：
我们的实验表明，一个连续的，线性的，电介质天线，其中超光速极化电流分布加速可以用来传输宽带信号，再现在一个可理解的形式，在选定的目标距离和角度。广播信号和接收信号之间精确对应的要求是，极化电流分布中的每个移动点在沿天线传输期间始终以光速接近目标。这导致在移动极化电流上的每个点进入天线的时间与由该特定点发射的辐射在其通过天线期间的{ \it all}同时到达目标的时间之间一一对应。这具有再现原始广播信号的期望时间依赖性的效果。对于其他观察者/检测器位置，由于发射（延迟）时间和接收时间之间的非平凡关系，信号的时间依赖性被扰乱。这种技术与传统的无线电传输方法形成对比;在后者的大多数示例中，信号以很少或没有方向性的方式广播，通过使用窄频带来实现接收的选择性。取而代之的是，目前的论文使用频率的扩展来将信息传输到特定的位置;信号较弱，并且在其他地方具有加扰的时间依赖性。我们指出了这种机制与5G邻域网络的可能相关性。这项工作也构成了一项地面天体物理实验，为脉冲星的发射机制提供了强有力的线索。
英文摘要：
We show experimentally that a continuous, linear, dielectric antenna in which a superluminal polarization-current distribution accelerates can be used to transmit a broadband signal that is reproduced in a comprehensible form at a chosen target distance and angle. The requirement for this exact correspondence between broadcast and received signals is that each moving point in the polarization-current distribution approaches the target at the speed of light at all times during its transit along the antenna. This results in a one-to-one correspondence between the time at which each point on the moving polarization current enters the antenna and the time at which {\it all} of the radiation emitted by this particular point during its transit through the antenna arrives simultaneously at the target. This has the effect of reproducing the desired time dependence of the original broadcast signal. For other observer/detector positions, the time dependence of the signal is scrambled, due to the non-trivial relationship between emission (retarded) time and reception time. This technique represents a contrast to conventional radio transmission methods; in most examples of the latter, signals are broadcast with little or no directivity, selectivity of reception being achieved through the use of narrow frequency bands. In place of this, the current paper uses a spread of frequencies to transmit information to a particular location; the signal is weaker and has a scrambled time dependence elsewhere. We point out the possible relevance of this mechanism to 5G neighbourhood networks. This work also constitutes a ground-based astrophysics experiment that gives strong clues towards the emission mechanism of pulsars.
