IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-FUNDAMENTAL THEORY AND APPLICATIONS
A synthesis technique of an equivalent lossless (nondispersive) uniform mul
ticonductor n-coupled lines (UMCLs) an-port system from the measured discre
te time-domain reflection response is presented, This procedure is based on
the decomposition of characteristic immittance matrix of UMCL in terms of
partial mode immittance matrices, The decomposition scheme leads to the dis
crete transition matrix function of a UMCL an-port system, This, in turn, e
stablishes a relationship between the normal-mode parameters of the UMCL an
d the measured impulse reflection and transmission response. Equivalence be
tween the synthesis procedure presented in this paper and the solution of a
special form of algebraic Riccati matrix equation whose solution can lead
to the normal-mode parameters and including real termination network is ill
ustrated, In order to exemplify the procedure, a typical microstrip structu
re with three lines is synthesized from the time-domain reflection (TDR) da
ta.
