Abstract :
The authors apply the method of moments in the spectral domain to the determination of the frequency-dependent scattering parameters of two-port microstrip circuits fabricated on magnetized ferrite substrates. The results presented show that it is possible to fabricate bandpass filters on magnetized ferrites that can be tuned by varying either the magnitude or the orientation of the bias magnetic field.
