Spread-Spectrum Selective Camouflaging based on Time-Modulated Metasurface
Xiaoyi Wang, Christophe Caloz
This paper presents the concept of spread-spectrum selective camouflaging based on time-modulated metasurface. The spectrum spreading is realized by switching the metasurface betwe…

Microwave Hilbert Transformer and its Applications in Real-time Analog Processing (RAP)
Xiaoyi Wang, Zoé-Lise Deck-Léger, Lianfeng Zou +2
A microwave Hilbert transformer is introduced as a new component for Real-time Analog Processing (RAP). In contrast to its optical counterpart, that resort to optical fiber grating…

Real-Time Spectrum Sniffer for Cognitive Radio Based on Rotman Lens Spectrum Decomposer
Xiaoyi Wang, Alireza Akbarzadeh, Lianfeng Zou +1
We introduce the concept of a Rotman-lens spectrum decomposer (RLSD) real-time spectrum-sniffer (RTSS) for cognitive radio. Compared to a previously existing RTSS, the RLSD-RTSS of…
