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…

Frequency Vectoralization and Frequency Birefringence
Alireza Akbarzadeh, Nima Chamanara, Christophe Caloz
In view of momentum continuity at a temporal slab, it is shown that instantaneous switching of an isotropic medium to an anisotropic medium offers the incident frequency a directio…
