Result of the theoretical calculations using the proposed passive detection scheme. (a) Example of the curve fitting of AlN at 11.8 μm. (b) Change in the effective polarizability with distance from an AlN surface at wavelengths of 10.5, 11.8, and 14.5 μm. (c) Change in the effective polarizability of the W-AlN (wavelength: 11.8 μm) and W-GaN probing system (wavelength: 14.1 μm). (d) Experimentally obtained vertical axis of the polarized sphere hp and polariton decay length of AlN (open circle, solid line) and GaN (filled square, dashed line).
