Abstract
We propose a new communications technology based on exploiting of the characteristics of propagation of evanescent waves, which typically are the non propagating part of the field. Here we demonstrate that evanescent fields do acquire semi-propagating characteristics in the presence of losses. In other words, we found that what is a hindrance for propagating waves happens to be a blessing for evanescent fields. Our main interest is in establishing broadband and low loss links. The lossy material environment will provide us with an optimum evanescent wave spectrum, and an antenna (eminently magnetic) will be designed so as to radiate the desired spectrum. We propose Metamaterials to enable us design an efficient miniature antenna. This is an important point, as the low frequencies require electrically very small antennas, which translate into high Q (narrowband operation) and low efficiencies (results of the so-called Harrington-Chu limitation). Our interest is in building a practical structure, and although our focus is in achieving a dramatic increase in communication range, our preference is for a rugged structure that can withstands the demands of underground or emergency environments; hence we will evaluate implementation aspects, as well as computationally assess the overall performance of the system.
