3. A single-input multiple-output waveguide microwave system, comprising one input port, a 1-to-N waveguide microwave network, multiple band-pass filters, multiple output ports and multiple accelerators, wherein,
the input port is configured to receive each of different input microwaves with different frequencies;
the 1-to-N waveguide microwave network comprises an input terminal and N output terminals, the input terminal of the 1-to-N waveguide microwave network is coupled to the input port, and the N output terminals of the 1-to-N waveguide microwave network are coupled to input terminals of the multiple band-pass filters, the 1-to-N waveguide microwave network is configured to perform matching;
output terminals of the multiple band-pass filters are coupled to the output ports, and are configured to pass or reflect the input microwaves according to the frequencies of the input microwaves; and
the multiple accelerators are coupled to the multiple output ports respectively, wherein the multiple accelerators are installed at different irradiation angles, switching between multiple ones of the different irradiation angles is implemented by adjusting the frequencies of the different input microwaves and selecting different ones of the multiple output ports for output to supply different output microwaves to the different accelerators.
