Development of leaky-wave antennas
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016This presentation overviews the development of leaky-wave antennas (LWAs) and the area of leaky waves, starting with the first LWA that was introduced and the early pioneering work of Marcuvitz and Oliner in explaining leaky-wave theory. The development leads up through the present time, where LWAs have seen a renewed interest in the context of ...

Security in terahertz WLANs with Leaky wave antennas
Proceedings of the 13th ACM Conference on Security and Privacy in Wireless and Mobile Networks, 2020This paper presents the first security study of THz networks with Leaky Wave Antennas (LWAs). We employ a mix of analytical models and over-the-air experiments to explore the unique security properties of LWA links. We show via both models and experiments that the LWA's angle-frequency coupling leads to non-uniform secrecy capacity across sub-channels ...

IEEE Transactions on Antennas and Propagation
A novel dual-band leaky wave antenna with a large frequency ratio of 3.4 is presented. The antenna is fed by an air-filled dual-mode-composite waveguide with a high structure reuse ratio in the two bands where only the TE10-like mode is supported.
