Future Trends on Nanoantennas Synthesis

This paper aims at outlining some possible future challenges and solutions in nanoantennas design in the range of applications going from millimeter to nanometer scale. The growing interest for such systems, both in the field of miniature sensors and for applications in the visible and near infrared frequencies, requires effective design procedure in order to satisfy the desired specifications and the feasibility constraints. In such a context, the paper presents some non-intuitive methodologies based on the swarm intelligence that could provide effective tools for nanoantennas synthesis. This is the author's version of the final version available at IEEE.
