Abstract (en)

Resonant coupling between the plasmonic excitation of gold nanoantennas and phonon polaritons of a dielectric
substrate-surface layer of about 3 nm thickness produces significant Fano-type signals from that layer in the
infrared extinction spectrum of the fundamental antenna resonance. Compared to infrared transmittance spectra
without gold antennas, the vibrational signal from the layer is about 1900 times enhanced and it is observed
at surface phonon polariton frequencies of the layer, not at the transverse optical phonon frequency.
