Effects of Electromagnetic Pulses on a Multilayered System

: Electromagnetic pulses (EMP) can be very destructive and protecting against them is crucial. This paper discusses a method to determine the effects an intentional EMP would have on a system with multiple layers of different materials by simulating the exposure to electromagnetic waves in ANSYS HFSS. Worst case scenarios are tested by applying wavelengths that result in a resonant frequency through the object. The results show the magnitude of the current densities at the surface of the object induced by the EMP waves. The impact of the waves can be determined by reviewing the current density through the object with respect to the physical properties of the materials.
