Figure 2a,b plots the spectra of the radiative and nonradiative powers, respectively, where d = 25 nm. These values are normalized by the radiative power of a free electric dipole in water without a scatterer. Table 1 presents the plasmon modes (dipole and quadrupole modes) and Fano resonances and dips that are obtained from these spectra. The Fano dip divides each of the dipole and quadrupole modes into bonding and anti-bonding modes. In Figure 2, the contributions of each order (n = 1, 2, 3,…) of the dyadic Green’s functions, which are series solutions in terms of spherical wave vectors, are

separated individually from the radiative and nonradiative powers: the dipole mode (n = 1), quadrupole mode (n = 2), sextupole mode (n = 3), octupole mode (n = 4), etc. In addition, the BACE inhibitor scattering cross section (SCS) and MLN2238 in vitro absorption cross section (ACS) are calculated using the Mie theory, as presented in Figure 3. The component of each order mode is also separated in Figure 3. These scattering and absorption efficiencies are the normalized SCS and ACS by the cross-sectional area, .

(b). Component of each order mode of nanomatryushka. [a 1 , a 2 , a 3 ] = [75, 50, 35] nm. Dipole mode Figure 2 shows a pronounced Fano dip in the radiative power (P r) spectrum at 740 nm and an accompanying peak (Fano resonance) in the nonradiative Thalidomide power (P nr) spectrum at 767 nm. Similarly, the SCS spectrum from plane wave illumination shows a Fano dip at 727 nm, and an accompanying Fano resonance is observed in the ACS spectrum at 765 nm (Figure 3). The Fano dip is the local minimum of P r and SCS, while the Fano resonance is the local peak of P nr and ACS; these two are very close to each other. These Fano behaviors are mutually consistent. For comparison, Figure 4a,b presents the corresponding radiative powers and SCS efficiencies of the Au core embedded in silica, nanoshell, and nanomatryoshka, respectively, where d = 25 nm.
