Modeling columnar thin films as platforms for surface-plasmonic-polaritonic optical sensing

, 2009
Via exploitation of surface plasmon polaritons (SPPs), columnar thin films (CTFs) are attractive potential platforms for optical sensing as their relative permittivity dyadic and porosity can be tailored to order. Nanoscale model parameters of a CTF were
