Mie void cavities show polaritonic spectra under resonant loading
—
in OpticsWhat the study found The study found that spherical Mie void cavities, including the inverse case of a void inside a resonant dispersive medium, can be analyzed for their resonant characteristics and polaritonic spectra. The authors report approximate analytical expressions for the Q-factors of these cavities and identify parameter ranges associated with weak and strong…
Terahertz pulse behavior in negative-index metamaterials is intensity dependent
—
in OpticsStudy reveals terahertz laser pulses create bright solitons below and dark solitons above a critical frequency in negative index meta-materials, with intensity-dependent bandwidth.
