| Popis: | In this paper, a statistical approach is proposed to estimate the radiated emission from an electronic system implemented on a printed circuit board (PCB). The radiated emission of the board is modeled by infinitesimal dipoles. The current of the modeling dipoles are estimated based on a statistical method using the power consumption of the board. The power distribution for each dipole is considered as Maxwell-Boltzmann function. Also, a definitive approach is proposed for estimation of power distribution on the board based on the location and power of each system constituting component. The method is verified by applied on a simple PCB and CST full wave simulations are done to compare the analytic method. An average error of 10% between simulation result and statistic method shows a moderate accuracy. The computational cost (memory and speed) of simulation is much better than full wave simulation for modern PCBs. Proposed method is suitable for a fast check to estimate the radiation level for complex PCB structures. |
