ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Bistatic MIMO Radar Clutter Suppression by Exploiting the Transmit Angle
The transmit angle of bistatic radars can be obtained by introducing Multiple-Input Multiple-Output (MIMO) radar techniques. The Three-Dimensional (3D) clutter spectra, that is, the transmit angle, receive angle, and Doppler frequency, are introduced ...

Dispersion‐Engineered Broadband Transparent Meta‐Cloak
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 ...

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
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.

Development of BREM Software for Bistatic Radar’s Range Estimations
A radar device is considered to be bistatic when the transmitter and receiver are placed on locations separated by a distance considerably greater than the distance from the target.
