<p>According to a waveguide connecting method, a shim (30) is fabricated to have a cylindrical portion (31) and flange (32). The cylindrical portion has an outer diameter substantially equal to an inner diameter of a first waveguide which is to be connected to a second waveguide. The flange projects from one end of the cylindrical portion outwardly. The other end of the cylindrical portion of the shim is inserted into the first waveguide. The second waveguide is urged against the first waveguide, with an end face of the second waveguide being in contact with the flange of the shim, until the end face of the second waveguide abuts against an end face of the first waveguide. A waveguide connecting structure is also disclosed.</p> |
