Abstract
This paper describes the electromagnetic field variance estimation in a random printed circuit board (PCB) model due to the unreliability in permittivity and conductivity of the substrate material using a stochastic finite difference time domain (S-FDTD) method. Traditional FDTD method is updated for mean and variance estimation of the electromagnetic field through the random medium by Taylor series approximation and delta method. The correlation coefficient between the constitutive properties is assumed as to bound the variance field. The 2D S-FDTD method is used for simulating variance of fields in PCB model, and the results are validated using Monte Carlo results.
