The Field Confinement, Narrow Transmission Resonances, and Green Function of a Multilayered Microsphere with Metamaterial Defects
Figure 2
(Color online) Comparison of the spectral properties of the transmission coefficients for 15-layered alternating stacks containing conventional (Si + SiO2) and (LH + SiO2) materials correspondingly (spherical number ): (a) the refractive index () for the Si (dotted line) and SiO2 (solid line); (b) the real (dotted line) and imaginary part (solid line) of the refraction coefficient for LH metamaterial. The spectrum is shown in (c) for conventional stack, while (d) shows for a combined stack when Si is replaced with LH layers. See details in text.
