Super-Robust Telecommunications Enabled by Topological Half-Supermodes. [PDF]
Adv Sci (Weinh)Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Phased Antenna Array Implementation with USRP [PDF]
2017 IEEE Globecom Workshops (GC Wkshps), 2017 This paper presents the implementation of a phased antenna array with Universal Software Radio Peripheral (USRP). The antenna elements of the array are driven by individual USRP platforms. Hence, the synchronization and calibration of different platforms are required in phase and amplitude.

POTENTIALITIES OF USRP-BASED SOFTWARE DEFINED RADAR SYSTEMS [PDF]
Progress In Electromagnetics Research B, 2013 Software Defined Radar is the latest trend in radar development. To handle enhanced radar signal processing techniques, advanced radars need to be able of generating various types of waveforms, such as frequency modulated or phase coded, and to perform multiple functions. The adoption of a Software Defined Radio system makes easier all these abilities.
