This paper introduces a metasurface-inspired antenna embedded in a circular metallic cavity with a very small diameter (from 0.25 λ0 down to 0.12 λ0, where λ0 is the wavelength in vacuum at the operating frequency). The proposed concept is introdu

International audience; Electromagnetic waves could carry orbital angular momentum. Such momentum can be transferred to macroscopic objects and can make them rotating under a constant torque. Based on experimental observations, we investigate the ori

Publikováno v: Microwave and Optical Technology Letters. 44:546-550

Most applications of electromagnetic band gap (EBG) concern antenna radiation or electromagnetic filters. In this paper, a metallic EBG structure is designed for stealth applications. We show how this structure allows us to reduce the radar cross sec
