Figure 5
Surface plasmon resonance wavelengths calculated for oblate and prolate silver spheroids of different aspect ratios in the glass matrix.
Red and black solid line show SPR wavelength for the light polarized along a- and c-axis, respectively. The following parameters were used for the numerical simulations: 
=4, λp = 135 nm, γ/ωp = 0.1[23], 
= 2.72.
