Wideband RCS reduction due to plasma generated by radioactive nuclei for cylindrical object

open access: yesScientific Reports, 2022
Radar cross section reduction has been one of the most important research topics in recent years. Plasma-based stealth is a method of reducing the radar cross section, which dampens the electromagnetic waves and reduces the amount of return waves.

REDUCTION OF RADAR CROSS SECTION BASED ON A METASURFACE [PDF]

open access: yesProgress In Electromagnetics Research, 2014
A metasurface for Radar Cross Section (RCS) reduction is proposed. The surface is composed of the same type of metamaterial units with difierent geometric dimensions, leading to various re∞ection phases under the incidence of plane waves. By carefully choosing the phase distributions, difiusion will be produced for the re∞ected waves which may ...
