Terahertz Magnetic Modulator based on Magnetically-Clustered Nanoparticles
Mostafa Shalaby, Marco Peccianti, Yavuz Ozturk +3
Random orientation of liquid-suspended magnetic nanoparticles (Ferrofluid) gives rise to zero net magnetic orientation. An external magnetic field tends to align them into clusters…
High harmonic generation in undoped graphene: Interplay of inter- and intraband dynamics
Ibraheem Al-Naib, J. E. Sipe, Marc M. Dignam
We develop a density matrix formalism in the length gauge to calculate the nonlinear response of intrinsic monolayer graphene at terahertz frequencies. Employing a tight-binding mo…
Ultrasensitive THz sensing with high-Q Fano resonances in metasurfaces
Ranjan Singh, Wei Cao, Ibraheem Al-Naib +3
High quality factor resonances are extremely promising for designing ultra-sensitive refractive index label-free sensors since it allows intense interaction between electromagnetic…
Limitation in thin-film detection with transmission-mode terahertz time-domain spectroscopy
Withawat Withayachumnankul
In transmission-mode terahertz time-domain spectroscopy (THz-TDS), the thickness of a sample is a critical factor that determines an amount of the interaction between terahertz wav…
Asymmetric planar terahertz metamaterials
Ranjan Singh, Ibraheem A. I. Al-Naib, Martin Koch +1
We report an experimental observation of three distinct resonances in split ring resonators (SRRs) for both vertical and horizontal electric field polarizations at normal incidence…
