High-Speed Terahertz Band Radio-Over-Fiber System Using Hybrid Time-Frequency Domain Equalization
IEEE Photonics Technology Letters, 2022The radio-over-fiber (RoF) orthogonal frequency division multiplexing (OFDM) system at Terahertz (THz) band has been a promising solution to meet the demand for high capacity and flexibility.

Defect Detection in Pipelines via Guided Wave-Based Time–Frequency-Domain Reflectometry
IEEE Transactions on Instrumentation and Measurement, 2021In order to improve the performance of the conventional guided wave testing (GWT) with a low sensitivity on damage in pipelines, a new GWT based on time–frequency-domain reflectometry (TFDR) is proposed. TFDR using electromagnetic signals is a diagnostic

A Hybrid Time/Frequency Domain Near-Field Chipless-RFID system
Mobile und Ubiquitäre Informationssysteme, 2022A novel encoding strategy for near-field chipless-RFID systems based on sequential bit reading is proposed in this paper. The tags consist in a chain of C-shaped resonators (inclusions) etched (or printed) at predefined positions in the tag substrate ...
