Applications of the “Classical” Metamaterial Model—Metamaterials with Interaction Between Meta-Atoms
The interaction between the small particles (meta-atoms), either dielectric or metallic, and the propagation of an optical excitation in a regular chain of such particles has been extensively investigated [1, 2, 3, 4, 5, 6]. Interest in the behavior of chains of metallic nanoparticles was driven mainly by the pursuit of subwavelength guiding structures for a new generation of the optoelectronic components in the area of communication and information processing. Nevertheless, theoretical tools for the modeling of these chains (irrespective to the nature and sizes) remain invariant: the electromagnetic excitation in the particles is supposed to be described by taking into account all possible eigenmodes [1, 3] and interactions between all particles in a chain.
