电磁波电场对金属表面交变电荷产生的单向推动力（一种无工质电磁推进模型）

彭立发

摘  要：本文提供一種模型，可将电磁波能量直接转化为动能，实现无工质推进。一个电偶极子在电磁波电场的作用下做无规则旋转运动，假设能把电偶极子正负电荷间距增加到电磁波的1/2波长，正负电荷在电磁波正反方向电场中会受到同方向的力，当电磁波电场方向改变时，正负电荷同步改变位置，可以继续产生同方向的力。将电偶极子换成金属天线（球形电容），金属天线馈入与电磁波频率和初相位相同的高频电压，当电磁波电场与金属天线接触时，电磁波电场对金属天线表面电荷产生电场力，当电磁波电场改变方向时，金属天线表面正负电荷同步改变，相当于共振，可以保证每个周期同步产生单方向推动力。可以证明本模型是电磁理论的推论。

Abstract： This paper provides a model which can directly convert the energy of electromagnetic wave into kinetic energy and realize the propulsion without working medium. An electric dipole rotates irregularly under the action of electromagnetic wave electric field. Assuming that the distance between positive and negative charges of the electric dipole can be increased to 1 / 2 wavelength of the electromagnetic wave， the positive and negative charges will be forced in the same direction in the electric field in the positive and negative directions of the electromagnetic wave. When the electric field direction of the electromagnetic wave changes， the positive and negative charges change their positions synchronously， and the force in the same direction can continue to be generated. The electric dipole is replaced by a metal antenna （spherical capacitor）， and the metal antenna is fed with a high frequency voltage with the same frequency and initial phase as the electromagnetic wave. When the electromagnetic wave electric field contacts the metal antenna， the electromagnetic wave electric field generates an electric field force on the surface charge of the metal antenna. When the electromagnetic wave electric field changes direction， the positive and negative charges on the surface of the metal antenna change synchronously， which is equivalent to resonance， and can ensure the safety of each antenna Periodic synchronization produces unidirectional driving force. It can be proved that this model is the inference of electromagnetic theory.

电磁波是一种不需要介质的能量波，由能量守恒定律，电磁波可以转换为其他能量，基本以热能为主。如果想把电磁波的能量直接转换为动能，目前还不能实现。英国的Shawyer在本世纪初研究了一种无工质微波推进装置Emdrive[1]，这个装置的理念就是将电磁波的能量直接转换为动能。中国的杨涓等[2-4]，美国的Brady等[5]也对此进行了系统研究，实验数据基本对应着电磁波动量表达式，但是他们并没有阐述产生极微弱压力的来源，不具有实际应用的力学价值。另外太阳帆的原理是利用了光动量作用或者说电磁波的辐射压力。……
