Advanced 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 ...

Far-field radar cross section determination using near-field ISAR imaging techniques
, 2022 4 S.Inverse synthetic aperture radar (ISAR) imaging is a powerful tool for the characterization of radar targets. Since the direct determination of the far-field radar cross section (RCS) typically requires expensive arrangements and equipment, short ...

Advanced Science, Volume 13, Issue 34, 19 June 2026.Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

Polarimetric Radar Cross-Section Imaging
, 2017 The radar cross-section (RCS) is a fundamental quantity which determines if a radar target can be reliably detected by a radar system. This quantity can be modified by altering the shape of the target.
