Abstract The rapid development of the Internet Things (IoT) has tremendously increased demands for wind speed sensors in various applications, such as weather forecasting and environmental monitoring. To date, many are developed based on triboelectric nanogenerators (TENGs). However, low output current leads to a poor sensing precision, which greatly limits their practical applications. Here, sensor is proposed by integrating wind‐driven triboelectrification‐induced electroluminescence...
We demonstrate optical control of surface plasmon enhanced resonant terahertz transmission in two-dimensional subwavelength metallic hole arrays fabricated on gallium arsenide based substrates. Optically pumping the creates a conductive layer substrate, reducing amplitude both mode and direct transmission. Under low fluence, is more greatly affected by resonance damping than propagation loss substrate. An ErAs:GaAs nanoisland superlattice substrate shown to allow ultrafast with switching...

We present resonant terahertz transmission in a composite plasmonic film comprised of an array subwavelength metallic patches and semiconductor holes. A large dynamic transition between dipolar localized surface plasmon mode resonance near 0.8 THz is observed under infrared optical excitation. The reversal amplitude from stop-band to pass-band up pi/2 phase shift achieved the make it promising modulation, changeover switching, active plasmonics.
We report the coupling between surface plasmons and dipole-localized in a composite hole-patch structure at terahertz frequencies.

Surface Plasmons are a special form of electromagnetic waves that propagate at metal-dielectric interface, and have promised various practical applications. plasmon based devices generally seen as next-generation integrated photonic devices.
