In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

To know the properties of a particle or a wave, one should measure how its energy changes
with its momentum. The relation between them is called the dispersion relation, which …

To realize the full promise of terahertz polaritonics (waveguide-based terahertz field
generation, interaction, and readout) as a viable spectroscopy platform, much stronger …

Optical pulling provides a new degree of freedom in optical manipulation. It is generally
believed that long-range optical pulling forces cannot be generated by the gradient of the …

Terahertz (THz) phonon polaritons, fundamental quasi‐particles that couple lattice vibrations
with electromagnetic fields at THz frequencies, are found in a variety of materials that offer …

In this article, an attempt is made towards the experimental validation of a numerical method
allowing vibro-acoustic and ultrasonic wave propagation analysis of complex woven …

The development of methods for the generation of strong ultrafast electromagnetic pulses in
the terahertz (THz) spectral range has led to a surge of progress in nonlinear THz …

We present a way for generating coherent tunable electromagnetic radiation through dc to
ac field conversion by an ionization front. The conversion is caused by the excitation of leaky …

We designed and implemented periodic bar arrays metamaterials to select appropriate
frequencies of terahertz (THz) waves propagating in a LiNbO_3 sub-wavelength waveguide …

The concept of the Brillouin zone (BZ) in relation to a photonic crystal fabricated in an
optically anisotropic material is explored both experimentally and theoretically. In …
