Abstract
The localized surface plasmon resonance positions and the Surface-Enhanced Raman Scattering (SERS) gain ($G_{SERS}$) of an ordered array of gold nano-cylinders with elliptic basis, embedded in a nematic liquid crystal (LC) media, are investigated using FDTD method. Structures are designed so that two resonances occur. The influence of the anchoring effects between nematic LC molecules and glass substrate on the shift of the double resonance wavelengths is taken into account, and results are compared with the case of a perfect alignment of the LC molecules and an isotropic material.
