We describe a systematic strategy for Brune's circuit synthesis of one-ports from positive real rational functions and its numerical implementation. Starting from numerical dataob- tained by measurement or from numerical full-wave simulation the rational function representation of Z- or Y-parameters is found using vector fitting procedure. Applying Brune's synthesis algorithm, a lumped element equivalent circuit is generated. Index Terms—Brune's circuit synthesis, Lumped element equivalent circuits Compact models of broadband distributed microwave cir- cuits are a valuable tool for efficient modelling and design of complex circuits. Lumped element circuit models are not only compact but also describe the physical quantities, like energy and power of the original structure (1)-(3).

The various approaches to the equivalent network synthesis of multiport microwave structure are discussed. For the estimation of the system's poles and zeros positions, the matrix system identification procedure in conjunction with the model order selection algorithm are introduced.

The former one is a dynamic linear system which describes the interaction of electric and magnetic fields inside the structure while the latter one is a linear system consisting of delay lines meant for the reflection and propagation. The system identification of the linear dynamic system needs the estimation of the poles positions and the maximum duration of the delays of complementary linear system. The improved system identification scheme based on poles set stability criterion is introduced. This scheme offers to divide the restored impulse response into the finite duration entire part and the infinite pole part which pertain to the each linear system correspondingly. The simulation results of the model parameter estimation for the two-port coplanar resonator are demonstrated.

The image can be modeled assuming the superposition of the identical partial responses from the effective target point-scatterers. Their positions correspond to the geometrical profile of target in the image coordinate plane. The proposed algorithm of radar image post-processing consists of the parametric and the non-parametric procedures which are used to improve the image resolution and to identify geometrical form of the target. The presented simulated results illustrate the main steps of radar image post-processing.

The band limited scattering parameters obtained by measurement or by full wave simulation was used for the network synthesis. This data could be represented by the transfer function of an equivalent circuit containing lumped elements (capacitors, inductances and resistances). The proposed approach is based on the simple description of the microwave structures using lumped element network. The submitted example of synthesis illustrates the microstrip filter design.
