By taking into account that the free electron has a fermionic character, we will write a non-linear Dirac-like equation describing the "motion" of this particle.
The Ionosphere can be considered as the region of the Earth atmosphere typically ranging from 50-70 km up to +1000 km, where there is a significant presence of ionized molecules, and free electrons (see Kelley 2009), being this presence high enough to affect space-based and ground-based radiofrequency signals, such as those of the Global Navigation Satellite Systems, GNSS (see for instance in Hernandez-Pajares et al.
The Navy had asked for 60 million dollars to continue with the research and development of these sci-fi weapons, but those plans could be altered based on the National Defense Authorization Act of 2012, which suggests 'terminating the Navy's free electron laser due to concerns over operational technical challenges.
