If you don't want multiple magnetrons (which would work too as a standard antenna in the wireless model of MIMO) you could use a electromechanical system, ie point magnetrons at reflective plates and move and adjust them to least direct the waves to a given point. Multi antennas I think would give a better granularity (because you can control the wave as well as direction and be able to time the peaks to hit inside a target vs just aiming the beams to a given spot). You may be able to get that with an electromechanical system, but it's not something I know of a lot of public info on, but if you could get a time division demux device for high power microwave that directs the different peaks to specific reflectors, you'd be good too.

Any openhard ware folks, please take this if you are interested!!!

In lighting effects an analogue could be a 'scanner', it reflects a stationary beam with a motorized mirror. Or you could mount the whole magnetron on a moving head!
