For instance, nanoparticles in a semi-infinite space undergo the influence of the AM of the beams, which are incident through prisms from the other semi-infinite space. Here, evanescent

In order to be charge neutral, the electrolyte contains equal amounts of anions and

The shift in the plasmon peak position will therefore be a result of the combined effect of the charge exchange and the change in dielectric properties of the YSZ.

The polarizability could be affected by the quality of the basis set, k-point sampling and the pseudopotential used (the plane-wave code uses a pseudopotential constructed with Cr in a d5s1 state, whilst the present calculations include s2p6d5s1).
