Characterization of higher harmonic modes in Fabry-Perot microcavity organic light emitting diodes.
Dahal E, Allemeier D, Isenhart B, Cianciulli K, White MS. Dahal E, et al. Sci Rep. 2021 Apr 19;11(1):8456. doi: 10.1038/s41598-021-87697-8. Sci Rep. 2021. PMID: 33875684 Free PMC article.
Employing a silicon wafer substrate with high thermal conductivity to dissipate excess heat in thicker cavities allows cavity thicknesses from 100 to 350 nm to be driven at high current densities. Three resonant modes, the fundamental and first two higher harmonics, …

Harmonic Amplitude Summation for Frequency-tagging Analysis.
Retter TL, Rossion B, Schiltz C. Retter TL, et al. J Cogn Neurosci. 2021 Oct 1;33(11):2372-2393. doi: 10.1162/jocn_a_01763. J Cogn Neurosci. 2021. PMID: 34272961
Following a transformation into the frequency domain, the brain's response is often evident at the frequency of stimulation, F, and its higher harmonics (2F, 3F, etc.). This approach is increasingly used in neuroscience, as it affords objective measures to character …

Dissociating harmonic and non-harmonic phase-amplitude coupling in the human brain.
Giehl J, Noury N, Siegel M. Giehl J, et al. Neuroimage. 2021 Feb 15;227:117648. doi: 10.1016/j.neuroimage.2020.117648. Epub 2020 Dec 15. Neuroimage. 2021. PMID: 33338621 Free PMC article.
We show that cross-frequency measures of phase-amplitude, phase-phase, and amplitude-amplitude coupling are all sensitive to signals with higher harmonics. In conjunction, these measures allow to distinguish harmonic and non-harmonic PAC. Based on thes …
