A faint radio glow reveals a million-light-year halo enveloping one of the earliest galaxy clusters, hinting that energetic ...

Fingerprint-based indoor positioning systems (IPSs) are being explored to aid in location-based services due to their robustness in nonline-of-sight (NLOS) conditions. Current systems use ...

A design technique is proposed for the topology generation of chipless radio frequency identification (RFID) tags. When the capacity of chipless RFID is as high as 21 bits, the chipless tag consists ...

So far, it is still challenging to realize a reconfigurable full-polarization metasurface cloak with multifunctional integration. Herein, we proposed an innovative metasurface cloak, which can ...
