Gg. Gentili et A. Melloni, ANALYSIS OF THE X-JUNCTION BETWEEN 2 RECTANGULAR WAVE-GUIDES AND A CIRCULAR WAVE-GUIDE, IEEE microwave and guided wave letters, 7(8), 1997, pp. 245-247
The paper describes a method for the analysis of the four-port junctio
n (X-junction) between two rectangular waveguides and a circular waveg
uide. The method is based on the computation by an efficient technique
of the generalized admittance matrix (GAM) of the structure (convenie
ntly divided into sub-blocks) with no restrictions on the geometrical
dimensions. a typical analysis with about 100 modes in the overall str
uctures requires 1-4 s per frequency point on a typical medium-power w
orkstation.
