Abstract
A spectral three-dimensional problem is solved to determine the resonant fr equencies of a branch formed by the orthogonal intersection of cutoff recta ngular waveguides. Expressions for the H-mng and E-mng modes are derived an d analyzed. Two classes of free nonradiating modes typical of this structur e are identified and analyzed. Numerical calculations are made of the dispe rsion relations obtained for the different modes. (C) 1999 American Institu te of Physics. [S1063-7842(99)01504-4].
