Electromagnetism can act as the model for futuristic antigravitation systems.

The electrons that are in extremely high energy levels can create gravitational waves. 

The ability to create synthetic gravitational waves by using a laser can make futuristic antigravitational engines possible. The idea is that the system shoots the gravitational waves against the dominating gravitational fields. If those gravitational waves travel in opposite directions that thing packs the gravitational waves between the craft and the dominating gravitational object. 

And that wave motion raises the craft above the ground. The system could make synthetic gravitational waves by stressing electrons by using laser systems. But the problem is that the electron's energy level must rise to extremely high. And then that system makes those extremely heavy electrons orbit each other. When those electrons that are (near the limit of) quantum size black holes. 

Orbit each other they send gravitational waves. Or otherwise, the electron can turn into a quantum size black hole, and when energy stress to that object ends. That thing causes the vaporization of that black hole. And at the same moment that black hole sends gravitational waves around it. So the needed thing is a laser that stresses electrons for enough long time. And when the energy stress ends that object sends the energy wave through the universe. 

The idea of that system is the same. When the magnet's south and south (or north and north) poles are turned against each other. Those poles are sending wave motion that starts to hover between the poles of magnets. And that thing causes the magnets are starting to repel each other. 

Electromagnetism can act as the model for futuristic antigravitation systems. 

When we think about the possibility to make the real anti-gravitation that denies the effect of the gravitation we can think of one other interaction. The electromagnetic interaction is the most well-known and common interaction that have also repelling and pulling effects. The electromagnetic interaction transportation particle is a photon. 

The problem with a photon is that it has no antiparticle. But the W-boson that transports weak interaction has anti-particle pair. The particles that are transporting the weak interaction are W+ (W-plus) and W- (W-minus) bosons. So there is the possibility that in some cases the W boson is the two bosons that are orbiting each other. 

When those particles are orbiting each other the (W-plus) boson will pull the minus pole of the neutron to it. And the (W-minus) boson pulls proton to it. But at the same time when the W-bosons are orbiting each other, they send wave motion away. The things that keep those bosons away from each other are the proton and neutrons. When proton and neutron are gone. Those particles could annihilate and form the photon. But that thing is not sure. 

All particles are sending wave motion. The frequency of that wave motion depends on the energy level of the particle. When the particle is stressed by using radiation that particle stores radiation. Until the energy level of the particle turns so high that its quantum field pushes radiation out.

And then it starts to send radiation or wave motion until its energy level is the same as its environment. The wave motion starts to travel when the energy pump to that particle ends. And particle sends extra energy as wave motion. 

The wave motion that is packed between the same poles of the magnet causes the repelling effect of the magnets. So could the gravitational waves cause a similar effect to crafts if they are packed between layer and the bottom of the craft? 

But when the opposite poles of the magnetic objects are pulling them to each other. The reason for that effect is the wave motion. When the object's poles are against opposite poles (minus pole against plus pole). That causes the wave motion starts to flow from the minus pole to the plus. (In this text north and south are replaced by words "plus" and "minus")

Wave motion that leaves from the object looks a little bit like a half-moon. Those waves are pulses that are traveling in one direction. And behind those pulses is the area with a lower energy level. That causes wave motion. And finally, the object is starting to travel in that channel. 

So that wave motion between minus and poles of the magnets pulls the particles to each other. The reason for that is that between those plus and minus poles forms a channel with a lower energy level. And then the wave motion behind those objects pulls the particles or objects together. 

But when the same poles are against each other that thing causes that electromagnetic interaction to push objects away from each other. The reason is that the magnets are sending the wave motion to the channel between them. 

That wave motion starts to flow in that area. And then that jammed wave motion forms the higher energy area between those minus and minus (or +and+) poles. After that, the area with a lower energy level pulls particles back. So the higher energy area between the same poles of magnets seems to pull the particles away. But the fact is that the lower energy area behind the object pulls the object back. 

Could we pack gravitational waves similar way between objects and the gravitational center?

So when we want to make a real antigravitation system. We must just find the gravitational waves that Earth will send. Then we should make the gravitational waves that have the same frequency as the incoming gravitational waves. And then just launch those gravitational waves against the dominating gravitational field. 

That should make the similar effect of standing and packed gravitation wavefield between object and dominating gravitation source. That thing makes it possible to create the hover of gravitational waves between objects and Earth. Those packed gravitational waves should act like in electromagnetism. And rise the craft hover over the ground.
