Prediction of electromagnetic waves scattering on complex shape large objects

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка
Relevance. Currently, the question radar cross-section (RCS) modelling of real targets arises. Experimental measurement is difficult to implement, and existing methods of theoretical calculation usually require a lot of time.

Wideband RCS reduction of thin metallic edges mediated by spoof surface plasmon polaritons

open access: yesEPJ Applied Metamaterials, 2021
The back-scattering from front edge diffraction contributes significantly to mono-static radar cross section under TE-polarization when the specular reflection of an object is eliminated by elaborate shaping.

Rare‐Earth–Sulfur Surface Modification Enables SiC Ceramics for Low‐Frequency Electromagnetic Wave Absorption in Extreme Environments

open access: yesAdvanced Science, EarlyView.
By altering surface chemical bonds to prolong relaxation time and shift absorption to lower frequencies, SiC/rare earth–sulfur (RE─S, RE = La, Ce, Pr, Sm, Gd, Er) materials achieve excellent low‐frequency electromagnetic wave absorption under extreme conditions, offering a new direction for designing high‐performance SiC‐based absorbers.

RADAR CROSS SECTION CHARACTERIZATION OF CORNER REFLECTORS IN DIFFERENT FREQUENCY BANDS AND POLARIZATIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Corner Reflectors (CR) are standard passive radar targets which offer one of the best solutions for SAR calibration. Radar Cross Section (RCS) of corner reflectors plays a vital role for estimation of calibration parameters and hence back scatter ...

Transparent metamaterial absorber with broadband radar cross‐section (RCS) reduction for solar arrays [PDF]

open access: yesIET Microwaves, Antennas & Propagation, 2020
Solar arrays are the primary energy source of the satellite. In this study, a metamaterial absorber for solar arrays with simultaneous high optical transparency and broadband microwave absorption is presented. By tailoring the reflection response of meta‐atoms, 87% absorption performance from 6.8 to 18 GHz is obtained.
