Abstract

The METHOD OF LEAST SQUARES is applied to the solution of the JUNCTION of cylindrical WAVEGUIDEs and its formulation is simplified. An error function is constructed from the boundary conditions (B.C.) at the JUNCTION which is a quadratic function of the modal amplitudes of the modal expansions inside the input and output guides. The unique minimum point of the error function gives the optimum conditions for the satisfaction of the JUNCTION B. C.'S. for the specified number of modes. A weighting factor is multiplied by the term due to the magnetic field B.C.'S. at the JUNCTION, which considerably affects the excited modal amplitudes and the field pattern at the JUNCTION. The conservation of REACTION is used to compute the equivalent JUNCTION susceptance and together with the conservation of complex power determine the optimum range of values of the weighting factor.The special problem of the step-up and step-down JUNCTION of coaxial circular WAVEGUIDEs containing a circular metallic iris with TE11 mode excitation is analyzed in detail and several computer programs are. written in the C language.The typical problems solved by MLS show very good satisfaction of JUNCTION B.C.'s. and the equivalent JUNCTION susceptances compare very well with experimental and numerical results available in the literature.
