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 and experimental data are processed for a...
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 means of both lumped element networks and...
Network oriented modeling of the passive microwave circuits provides a useful representation of the circuit and leads to the reduction of the required computer time and memory capacity. The proposed stability criterion allows dividing the simulation or measurement results into two parts representing a lumped elements model and distributed parameters model. The system identification procedure defines...
The full wave time-domain numerical simulation of the 3-D electromagnetic structure yields wide band reaction of the multiport microwave circuit on the input electromagnetic signal. The realization of the system identification procedure demands the preliminary determination of the late-time border and the order of the pole model. The new criterion for their estimation is offered. This criterion is...
In this paper an advanced ultra-fast broadband time-domain EMI (TDEMI) measurement system based on a multi-level analog-to-digital converter (ADC) is presented. The proposed multi-level quantization system is compared with a single ADC system. The multi-level system is modelled and investigated experimentally in the 30-1000 MHz frequency range. Measurement results and the results of computer simulations...
