Phonon-polaritons offer an exciting avenue in nanophotonics. We comment on the novel nanofabrication approach presented by Bo Qiang et al. in this issue of Advanced Photonics. Their approach to phononic material allows better radiation manipulation
When a dielectric meta-atom is placed into a subwavelength metallic aperture, 20-fold enhanced electromagnetic transmission through the aperture is realized at the meta-atom’s resonant frequency. Additionally, when the incident electromagnetic power incre
Gait recognition has been of great importance for disease diagnosis, rehabilitation assessment, as well as personal identification. Conventional gait analysis generally has to rely heavily on complex, expensive data acquisition and computing apparatus. To
