An LFM-Based Semiblind Synchronization Method for Bistatic Radar Imaging

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Bistatic radar provides an additional degree of freedom in the observing geometry for imaging by using a spatially separated transmitter and receiver. This capability allows the capture of scattering phenomena at various bistatic sensing angles, which ...

Target Coordinates Estimation by Passive Radar with a Single non-Cooperative Transmitter and a Single Receiver [PDF]

Journal of Communications Software and Systems, 2020
Passive radar is a bistatic radar that detects and tracks targets by processing reflections from non-cooperative transmitters. Due to the bistatic geometry for this radar, a target can be localized in Cartesian coordinates by using one of the following ...

Dispersion‐Engineered Broadband Transparent Meta‐Cloak

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Achieving broadband performance remains a critical challenge in engineering physics. Here, theoretical derivation shows that the core phase compensation conditions for broadband transparent cloaking exhibit dispersive characteristics. A novel broadband transparent cloaking paradigm via dispersion engineering is proposed, and a meta‐cloak that realizes ...

Hierarchical Reconfigurable Metasurface Based on Scenario‐Guided Functional Modules and Programmable Core

Advanced Science, Volume 13, Issue 28, 18 May 2026.
This paper proposes a hierarchical reconfigurable metasurface architecture (HRMA) to achieve comprehensive electromagnetic parameter modulation and on‐demand polymorphic function switching. The reconfigurable metasurface is divided into a programmable core (PC) and scenario‐guided functional modules (FMs), exhibiting significant flexibility and ...

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity

Electron, Volume 4, Issue 2, May 2026.
This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.

Synergistic Optimization of Microwave Absorption and Thermal Properties via Morphology Control in Tin Disulfide Coated FeCoCrNiAl Powders

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT This study employed a FeCoCrNiAl high entropy alloy matrix to regulate the nucleation and growth of SnS2 through solvent polarity, viscosity, and sulfur source release rates. Three distinct nanostructures including nanoribbons, nanoflowers, and nanosheets were synthesized and integrated onto a silicone rubber substrate.
