Communication theory and resonances on electromagnetic systems

We have shown that some electromagnetic systems allow specific frequencies to satisfy special equivalent conditions to make use of a left hand material. We called these frequencies resonances because of their properties, similar to those solutions of the homogeneous Fredholm´s equation for nuclear physics. But the process of information transmission requires not only the envoy of a limited number of frequencies but a very broad set of them. To answer the question of how we can use the knowledge of the resonances on a real system, we make use of the communication theory and the other properties, like the super-oscillating addition of functions and the mathematical deformation of the contour of the spectral representation of signals in order to create a set of frequency packs labeled with the final effect to optimize the information broadcast. In this paper we also suggest how we can preserve the convenience of this resonant point of view even when we cannot guaranty that the resonant conditions can be sustained permanently.
