I designed a new kind of eletric thruster. According to my calculations, its thrust can be much higher than radiation pressure.

The principle is: We know that on the electromagnetic wave propagation path, the direction of electric field at a point changes periodically. If there is a charged object at the point also changes its charge property periodically with the same frequency, then the electric field force direction on the object will not change. Therefore, the object will do directional movement. Based on this, it is possible to design a spacecraft without propellant. And the calculation suggests that the thrust can be much higher than radiation pressure.

It seems impossible, but my calculation suggests that it is possible. Can someone explain it?
