Schematic of the growth of a columnar thin film (CTF), which is an assembly of parallel nanocolumns tilted at angle χ with respect to the substrate plane. The direction of the collimated vapor flux is quantitated through the angle χv. The morphologically significant plane is shown.

Schematic of the Turbadar-Kretschmann-Raether (TKR) configuration wherein a substrate-metal-CTF sample is affixed to the base of a prism. An index-matching liquid is placed between the substrate and prism. A p-polarized THz plane wave is incident on one slanted face of the prism at an angle ϕ. The intensity of the light exiting the other slanted face of the prism is measured through a photodetector–oscilloscope combination. Either air or a fluid occupies the void regions of the CTF.

Overall reflectance R measured as a function of θ when a p-polarized THz plane wave is incident on one slanted face of the prism in the TKR configuration, when either (a) air, (b) water, or (c) M sucrose solution occupies the void regions of the CTF. Solid red lines are for the samples containing a 750-nm-thick CTF, dot-dashed blue lines for the samples containing an 1100-nm- thick CTF, and dashed black lines for the samples containing a 1500-nm-thick CTF. An arrow identifies the estimated value of θSPPCTF in each panel. Figure Legend: From: Surface plasmonic polaritonic sensor using a dielectric columnar thin film J. Nanophoton. 2014;8(1): doi: /1.JNP
