Scattering, absorption, extinction, and local field efficiencies ($Q_{SCA}\left(\omega \right)$, $Q_{ABS}\left(\omega \right)$, $Q_E\left(\omega \right)$, $Q_{NF}\left(\omega \right),$ respectively) for a silver nanoparticle with radius $a$ = 22 nm immersed in water. These quantities are proportional to the corresponding cross-sections (i.e., $Q_{SCA}\left(\omega \right)=\frac{{\sigma }_{Sca}\left(\omega \right)}{\pi a^2}$ and similarly for the others).
