AN ACCURATE FIELD MATCHING ANALYSIS OF WAVE-GUIDES OF COMPLEX CROSS-SECTIONAL GEOMETRY LOADED WITH MAGNETIZED FERRITE RODS

Many structures, such as ferrite phase shifters and rectangular wavegu ides loaded with ferrite or dielectric rods of circular cross-section are difficult to analyze. We have developed a field-matching technique capable of analysis of waveguides of complex cross-sectional geometry comprising longitudinally magnetized ferrite rods. The method has bee n implemented on a PC computer equipped with a Microwave i860 board. C omputations of inner products by FFT resulted in three-fold increase i n computational speed and two-fold reduction of computer memory requir ed. The method provides results with high accuracy and within a reason able computing time. Convergence properties, numerical and experimenta l results are presented.
