Electron Delocalization Induced by 3d–4f Orbital Hybridization of Co─Ce Atom Pairs Toward Enhanced Electromagnetic Wave Attenuation and Antibacterial Performance

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
Co─Ce dual atomic configuration anchored on the surface of NC matrix has been constructed to regulate the local electron structure. The higher occupied states induced by the Co 3d‐Ce 4f orbital hybridization facilitate the formation of polarized electric fields, which in turn strengthens the polarization relaxation and partially repairs the effective ...

Radar Cross-section Measurement Techniques [PDF]

open access: yes, 2010
Radar cross-section (RCS) is an important study parameter for defence applications specially dealing with airborne weapon system. The RCS parameter guides the detection range for a target and is therefore studied to understand the effectiveness of a ...

Analysis and Reduction on in-Band RCS of Fabry-Perot Antennas

open access: yesIEEE Access, 2020
In this article, a method is proposed to reduce the in-band radar cross section (RCS) of the high-gain Fabry-Perot antenna (FPA) based on the cancellation between the antenna mode RCS (AM-RCS) and structural mode RCS (SM-RCS).

Terahertz radar cross section measurements [PDF]

open access: yes, 2010
We perform angle- and frequency-resolved radar cross section (RCS) measurements on objects at terahertz frequencies. Our RCS measurements are performed on a scale model aircraft of size 5-10 cm in polar and azimuthal configurations, and correspond ...

Polarimetric calibration strategy for long-duration imaging with a ground-based SAR [PDF]

open access: yes, 2005
The Ground-Based Synthetic Aperture Radar (GB-SAR) facility in the UK provides high-resolution, fully polarimetrically calibrated L- through X-band SAR imagery, principally of targets of remote sensing interest such as soils and vegetation.

Radar cross-section analysis of wind turbine blades with radar absorbing materials [PDF]

open access: yes, 2011
Wind turbines interfere with radar systems due to their large radar cross-section (RCS) and the rotation of the blades. Applying radar absorbing materials (RAM) is considered as a possible mitigation measure.

Optimal Path Planning for UAVs to Reduce Radar Cross Section [PDF]

open access: yes, 2007
Parameter optimization technique is applied to planning UAVs(Unmanned Aerial Vehicles) path under artificial enemy radar threats. The ground enemy radar threats are characterized in terms of RCS(Radar Cross Section) parameter which is a measure of ...
