The Field Confinement, Narrow Transmission Resonances, and Green Function of a Multilayered Microsphere with Metamaterial Defects
Figure 7
(Color online) The field structure for various resonances (numerated as ) produced by a defect in the forbidden frequency gaps. (a) shows the spectrum of transmission coefficient for the periodic multilayers microsphere system composed of 15 alternating layers of LH and SiO2 and a LH defect placed in the center of the stack. In (b), (c), and (d) show the radial dependence of the field (arbitrary units) on corresponding to the resonant peaks marked in (a) as , respectively. The dashed lines in (b), (c), and (d) show the structures of the spherical stack (refractive indices). The spherical number is , is radius of the internal bottom microsphere.
