Proceedings ArticleDOI
Wake-field studies on photonic band gap accelerator cavities
TL;DR: In this paper, the wake-field of several metal Photonic Band Gap (PBG) cavities is studied and compared with that of a cylindrical pill-box comparison cavity.
Proceedings ArticleDOI
Optimised lambda architecture for monitoring WLCG using spark and spark streaming
TL;DR: Suthakar et al. as mentioned in this paper also acknowledge the IEEE NSS-MIC for financial support in the form of a Trainee Grant, which they used for their work.

Journal ArticleDOI
3D Conductive Polymer Printed Metasurface Antenna for Fresnel Focusing
TL;DR: In this paper, a 3D printed holographic metasurface antenna for beam-focusing applications at 10 GHz within the X-band frequency regime was demonstrated. And the authors demonstrated that using a dual-material 3D printer leveraging a biodegradable conductive polymer material (Electrifi) and polylactic acid (PLA) to print the dielectric substrate, high-fidelity beam focusing can be achieved within the Fresnel region of the antenna.
Journal ArticleDOI
2D Ray Tracing Analysis of a Dynamic Metasurface Antenna as a Smart Motion Detector
TL;DR: A ray-tracing analysis of a smart motion detector based on a dynamically reconfigurable metasurface antenna based on an array of metamaterial radiators excited by a single-port waveguide or cavity is presented.
