A High-Gain Filtering Fabry-Perot Antenna With RCS Reduction

IEEE Access, 2023
A high-gain filtering Fabry-Perot antenna (FPA) with radar cross Section (RCS) reduction is proposed. The design utilizes a partially reflecting surface (PRS) which is integrated with a chessboard arranged metasurface (CAMS) in a single-layered substrate.

Chessboard reflector for RCS reduction

Electronics Letters, 2008
It is shown that a simple interlaced pattern of doubly periodic square metal and dielectric patches constructed on a high dielectric constant substrate can redirect electromagnetic energy which is normally incident onto the surface away from boresight, thereby giving a means for RCS control.

RCS REDUCTION OF QUASI-YAGI ANTENNA [PDF]

Progress In Electromagnetics Research C, 2014
A novel Quasi-Yagi antenna with low radar cross section (RCS) is proposed in this paper. By using arrow-shaped Koch dipoles as the driver and director and cutting the ground of the antenna, the RCS can be reduced in the operating band of 5 GHz-8 GHz when the incident wave is perpendicular to the antenna plane.

Coding metasurface for diffusion‐like scattering in multiple directions based on Pancharatnam–Berry phase

Nano Select, 2022
Diffusion‐like scattering along multiple directions based on coding metasurface (CM) is proposed for both mono‐static and bi‐static radar cross section (RCS) reduction in this work. Different from the previous CMs achieving diffusion‐like scattering only

Randomized preclinical study of machine perfusion in vascularized composite allografts

BJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.
