| Popis: | An equation-based hybrid method combining field equations with circuit solver is proposed for characterizing the radiated susceptibility problems associated with the RF/microwave circuits, which are illuminated by a uniform plane incident wave. First, the analytical expressions for equivalent voltage and current sources are developed for discussing the global effect of the incident plane wave on the associated microstrip line elements. Then, by incorporating these field-induced equivalent source expressions into a commercial circuit solver, one may establish a fast model for analyzing the RF/microwave circuits with active and passive components. In this paper, the proposed model is used to characterize the microstrip circuits, such as the cross bend and RF amplifiers. The proposed model is also validated by comparing the results from both simulation and measurement and good agreement between them is observed. With the merit of short simulation time, the proposed fast model would be very efficient in discussing the radiated susceptibility problems associated with the analog/digital modulated circuits. |
