T1 A SCHWARZ ALGORITHM FOR THREE-DIMENSIONAL DIFFRACTION PROBLEMS JF Telecommunications and Radio Engineering JO TRE YR 2015 FD 2015-04-14 VO 74 IS 1 SP 1 OP 8 K1 wave diffraction; waveguide junctions; stepwise discontinuities; Green functions; Schwarz iterative methods AB The diffraction of an electromagnetic wave by a co-axial junction of two rectangular waveguides of different cross-sections is treated within a version of the Schwarz method. An explicit formula is derived for the k-th iteration of the complex reflection coefficient of the TE01 mode. The absolute value of the reflection coefficient is calculated numerically for a variety of magnitudes of the α/λ parameter, and the algorithm convergence is analyzed.
