Abstract :
The analysis of effects from noise illumination of electrical and electronic systems is complicated by stochastic rather than deterministic variables. An analysis technique is presented for noise propagation, where the noise is modeled as a time series of discrete time impulses with amplitudes computed by a white Gaussian noise simulation. Using the noise source to simulate the drive of an appropriate antenna, the analysis of the radiated noise signal is accomplished through the use of the finite-difference time-domain (FDTD) formulation. The presented technique is verified by a comparison with the results obtained from using the method of moments and a wire antenna radiator. In addition, limitations, stability, and applicability of the presented formulation are discussed
