A Simple Design of Polarization Reconfigurable Fabry-Perot Resonator Antenna
IEEE Access, 2020 This paper presents a simple design of high gain Fabry-Perot (FP) antenna with polarization diversity. The proposed antenna is composed of a reconfigurable microstrip patch, a partially reflective surface, and a planar metallic reflector. By electrically

Compact Bent-Corner Orthogonal Beam Switching Antenna Module for 5G Mobile Devices [PDF]
Journal of Electromagnetic Engineering and Science, 2022 Typically, users engage with smartphones in either single-hand or dual-hand mode. To design antennas that operate at 28 GHz and have high pattern integrity for both modes of operation, an orthogonal beam switching module is required as a single phased ...

High-Gain High-Field Fusion Plasma [PDF]
Scientific Reports, 2015 AbstractA Faraday wheel (FW)—an electric generator of constant electrical polarity that produces huge currents—could be implemented in an existing tokamak to study high-gain high-field (HGHF) fusion plasma, such as the Experimental Advanced Superconducting Tokamak (EAST).

Gain and Dispersion Focusing in a High Gain Laser [PDF]
Applied Optics, 1972 The transverse modes of a laser resonator containing a medium with a strong radial gain profile differ greatly from the modes of a similar resonator containing a low gain medium. Focusing and defocusing effects result from the gain profile and from the associated dispersion profile. The dispersion focusing causes an asymmetry in the power output as the

High‐gain polarization conversion metasurface
ETRI Journal, 2019 A novel analytical method based on the cavity mode theory to design a metasurface (MS) is proposed in this study. We carefully analyzed the phase and amplitude characteristics of the incident wave and transmitted wave, and successfully designed a ...
