Abstract

The effect of induced voltages due to electromagnetic pulses is studied with the combination of commercial electromagnetic simulation software (MEFISTo) and uncertainty modeling. The uncertainty is introduced using the Unscented Transform technique for two random variables: the relative permittivity and conductivity of the soil. These were modeled as independent random variables with uniform distribution. The results were the statistical moments of the induced voltage (expected value and standard deviation) as well as an estimate of the cumulative distribution function.
