In this paper, metallic plasmonic nano-antennas are modeled and analyzed for wireless optical communication. More specifically, a unified mathematical framework is developed to investigate the performance in transmission and reception of metallic nano-dipole antennas. This framework takes into account the metal properties, i.e., its dynamic complex conductivity and permittivity; the propagation properties...
In this letter, a theoretical model is proposed to calculate the coupling efficiency of surface plasmon polaritons (SPPs) by a single slit on the metal film. In contrast to previous work developed for normal incident light only, TM0 and TM1 modes of the slit are incorporated in the model, which makes it applicable for the case of oblique incidence. Numerical simulations confirm that this two-mode...
Breaking the symmetry in plasmonic nanoparticles offers additional degrees of freedom that can be utilized to increase the tunability of such nanoparticles. Metallic shells with non-concentric dielectric cores possess such properties, where the core displacement affects the wavelength at which plasmon resonance occurs. It remains important to have analytical formulation for the properties of such...
