  2. 1. Effects of surface plasmons in subwavelength metallic structures

    Author : Srinivasan Iyer; Ari T. Friberg; N. Asger Mortensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; suface plasmons; extraordinary transmission; metamaterials; shnets; split-ring resonators; plasmon-induced EIT; optical antennas; plasmonics;

    Abstract : The study of optical phenomena related to the strong electromagnetic response of noble metals (silver (Ag) and gold (Au) being most popular) over the last couple of decades has led to the emergence of a fast growing research area called plasmonics named after 'surface plasmons' which are electron density waves that propagate along the interface of a metal and a dielectric medium. Surface plasmons are formed by the coupling of light to the electrons on the metal surface subject to the fulfillment of certain physical conditions and they are bound to the metal surface.
