the only way to make them work as advertised is to sync the fields so they occur at exactly the same time. A master clock if you will, and entirely sinusoidal, not square waved.
so one needs a sine generator as a master clock and then to couple the output of the that generator to multiple antenna.
to also create the harmonics of the field as well, so, third time's the charm:... it's a sine generator with matching correct harmonics and a set of coupled antennas.
Then.... it's a proper multiple generator set up.
