The representation of electromagnetic structures by lumped element circuits is revisited. Network models can be established by a subsequent application of system identification and circuit synthesis methods to data obtained by numerical simulation or from measurement. Network models provide a compact description of electromagnetic structures and can… (More)
In this paper we present the time domain computation of the impulse response of optimized antenna structures using the transmission line matrix TLM method. Hybrid extensions based on system identification (SI) are a means to reduce the computational burden considerably. Model-based SI procedures can be used to represent complex electromagnetic structures by… (More)
Network oriented modeling of passive microwave multiports provides a useful representation of the linear device and leads to the reduction of the required computer time and memory capacity for the synthesis procedure. The Brune's multiport method allows to represent the microwave structure in the predefined frequency band as a combination of the lossless… (More)
This paper describes two approaches to equivalent network synthesis for multiport microwave structures used limited band data of Z matrix. The proposed approach is based on the simple description of the microwave structures using lumped element network. The synthesis illustrated by the example of the microstrip filter design.
The paper suggests combining the inverse filtering and the parametric identification in the post-processing sequence of the complex radar image. 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… (More)
Integrated nanoantennas for sensorics and communications on the basis of CMOS circuits, MIM tunnel diodes, and carbon based nanoelectronics as well as methods for modeling of wireless interchip links are discussed. Experimental validation of the modeling methods is presented.
In this paper a method to derive lumped-element network models for distributed microwave circuits by means of system identification is presented. This procedure has been applied to a 4-port integrated transformer circuit the purpose of which is to feed an on-chip planar dipole antenna for chip-to-chip wireless communication. The resulting network topologies… (More)
In this paper Brune's multi-port synthesis is treated systematically. The method allows to synthesize linear passive reciprocal multi-port circuits using lumped element RLC networks containing only positive circuit elements.
A two dimensional localization algorithm for stochastic EMI sources based on time domain measurements of electromagnetic near-field tangential components is presented. The autocorrelation and cross-correlation functions obtained by using the two-point planar scanning system are used for the characterization of stochastic field distribution. The simulation… (More)
Second order CS stochastic processes are non-stationary stochastic processes, where the TDCM depends on the global time and the time difference, and the dependence on the global time is periodic. This autocorrelation function can be represented by a 2D cyclic correlation spectrum containing delta functions at frequencies multiple to the cycle frequency of… (More)
