MAGNETIC LOSSES IN STRIPLINE MICROSTRIP CIRCULATORS/

We have included losses in the analysis of a 3N-port stripline/microst rip circulator and have reformulated the circulation conditions previo usly postulated for the lossless case. Our calculations have been comp ared to three published data on circulator designs biased below and ab ove ferrimagnetic resonance. Scattering parameters at each port have b een calculated as a function of assumed material losses and coupling c apacitance of a multiport circulator. Wide transmission band or wide s top bands may be possible for a six port circulator biased above ferri magnetic resonance. (C) 1996 American Institute of Physics.
