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 𝑇 for 15-layered alternating stacks containing conventional (Si + SiO₂) and (LH + SiO₂) materials correspondingly (spherical number 𝑚=1): (a) the refractive index 𝑛(𝜔) (𝑓=𝜔/2𝜋) for the Si (dotted line) and SiO₂ (solid line); (b) the real (dotted line) and imaginary part (solid line) of the refraction coefficient 𝑛(𝜔) for LH metamaterial. The spectrum 𝑇(𝜔) is shown in (c) for conventional stack, while (d) shows 𝑇(𝜔) for a combined stack when Si is replaced with LH layers. See details in text.
