Application of the Stability Criterion to the Passive Electromagnetic Structures Modeling

Network Oriented Modeling of Passive Microwave Structures

“…Another way to find the frequency characteristic is the deconvolution in time domain of the incident a(t) and return b(t) waveforms obtained by the full wave TLM simulation and the subsequent Fourier transform of the result [1], [6].…”

“…, p N } in N -dimension space, where each dimension describes one pole complex number coordinate. Therefore the distance between two points P 1 = p (1) n and P 2 = p (2) n can be defined as…”

“…Results of the full-wave electromagnetic simulation or time domain field measurements can be considered as initial data for the subsequent system identification. The first proceeding step is the obtaining of IR by the deconvolution in the required frequency range [1]. The obtaining of such IR provides the microwave structure description which is free of ill-condition problems.…”

“…The division of the full reaction into two parts can be implemented by proposed stability criterion [1]. This criterion is based on the fact that all scattering processes inside the electromagnetic structure (EMS) are concentrated in a relatively short duration interval at the beginning of the time-domain reaction.…”
