Significance of randomness in establishing hotspots in crystals

Abstract

Microwave scattering in random mediums is known to result in localized energy concentrations known as hotspots. However, the mechanics behind this effect are not well understood. Abstractions are needed to manage the complexity required to develop understanding through simulation and lead to the establishment of the parameters for a microwave system to neutralize energetic materials. Here, two random contributions of rotation and translation are separately simulated. It is observed that the individual effects both contribute to localization, and the combined effect is greater than the sum of the individuals.
