Mode coupling coefficients are the bases of coupled-wave theory (CWT). The mode coupling coefficients in coaxial waveguide with radii changes were deduced. It is revealed that the mode coupling coefficients in circular waveguide are just the special cases of those in coaxial waveguide. The coaxial waveguide modes and their eigenvalues were analyzed. The eigenvalues calculating method was obtained by constructing the corresponding relation between coaxial waveguide modes and rectangular waveguide modes. The mode coupling coefficients formulae were validated by the finite-element method (FEM). The calculation results of CWT agree well with that of FEM.
