Speculation – Does There Exist Point To Point Radio Transmission?

We can direct electricity in a circuit by changing the potential at different points.

Therefore I wonder if radio waves. Since I guess they are somewhat spherical. Instead feel the same potential at all the surrounding points.

If so then I guess it might be possible to change the surrounding potentials instead of using a directional antenna.

The advantage I guess is that the aim is a lot easier then.

Like point to point transmission.
