    • One reason for this limited accuracy is the finite size of the rectangular elements that represent the ellipsoid, particularly when the ellipsoid is very small. The effective aspect ratio r of the finite-element model may be smaller than the expected ratio r = 3, which then yields a smaller enhancement γ.

    • For small ellipsoid dimensions, the number of rectangular elements that map the ellipsoid is limited. The effective aspect ratio can vary by ±5%. Since the plasmon resonance is so strongly dependent on the aspect ratio according to Eq. (1), the difference found between FETD and the analytical value is acceptable.

    • We have also repeated the exact conditions as found in Refs. 19 and 20 and found a significantly lower field enhancement γ-about 10x.
