HOW to design a waveguide power divider?

I want to design a wave power divider at 4.4GHz to 5GHZ,but I have no resource.
One to Two is possible. if you have an example or resource ,please send to me,

Hi, I have several papers for you

1st one is "Synthesis of a compound T-junction for a two-way splitter with arbitrary power ratio"

2nd one is "The modified stepped waveguide T-junctions and the method of initial design"

3rd paper is "Design of unequal H-plane waveguide-power dividers for array applications" at https://www.edaboard.com/viewtopic.p...031790#1031790

All of them are T-shap

Additional paper is "Waveguide diplexer using E-plane tee of improved symmetry", that mentions about a Y-shap waveguide power divider.

Hope it helps
