Numerical Evaluation of the HEMP Diffusion into Buried Infrastructures

The use of High Altitude Electromagnetic Pulses (HEMP) as a threat to society has prompted the scientific community to produce methodologies to address the electromagnetic compatibility (EMC) of installations against radiated and conducted interference with frequency and amplitude ranges that may differ from traditional sources of disturbance, such as lightning, industrial noise, or communications broadcasting. This has led to a trend toward providing more effective modeling strategies for studying the response of large complex systems. The main issues that arise when analyzing such systems are the significant amount of memory and CPU time required to process these simulations and the ability to include physical models of generally neglected components (materials, vents, slots) that are necessary to obtain an accurate description of current distributions [1].
