Simulate the variability of equipment with the MKME

This article deals with a method that offers the possibility to simulate and estimate the impact of a component change in a complex system on its electromagnetic signature. To realise the modelling, the MKME (Modified Kron´s Method for Electromagnetic) is the method chosen for the topological analysis of the complex systems. This method is combined with change-of-basis matrix allowing connections and disconnections of sub-systems inside the system. After a brief review of the Kron´s method, we will define the process to use. At first, the minimal description for sub-system will be detailed, and then the application of the change-of-basis matrix that allows combining the sub-systems to generate the whole complex system. This method uses the electromagnetic analytical coupling functions and once the topology and the functions of interaction constructed, it´s easy to take into account any variation in the system.
