  • SHORT-RANGE WIRELESS COMMUNICATION METHOD AND RELATED DEVICE
    Publication number: 20240089156
    Abstract: This application provides a short-range wireless communication method and a related device. The method includes: generating a transmission frame. The transmission frame includes a frame header and a data domain, phase shift keying modulation is used for the frame header, and quadrature amplitude modulation or phase shift keying modulation is used for the data domain. The method includes sending the transmission frame. In this application, the phase shift keying modulation is used for the frame header of the transmission frame, and the phase shift keying modulation or the quadrature amplitude modulation with a same bandwidth is used for the data domain.

  • Ultra-wide band slow light structure using plasmonic graded grating structures
    Patent number: 8208191
    Abstract: A slow light system includes a substrate and a metal layer formed thereon, the metal layer having a graded grating structure formed at a surface thereof, wherein the grating depth of the grating structure is sized such that surface-plasmon polariton dispersion behavior of the grating structure differs at different respective locations along the grating structure. Different wavelengths of incident light waves can be slowed at the respective locations along the grating structure.
