Permafrost and Periglacial Processes, EarlyView.ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.

Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning
Nanophotonics, Volume 15, Issue 14, 27 July 2026.This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract The deployment of a multistatic radar network in the Oklahoma City metropolitan area in Spring 2024 has allowed for unique observations of several severe weather events. This passive multistatic network operates in conjunction with the operational KTLX WSR‐88D, allowing for synchronous multi‐Doppler analyses. This work presents a case study of

An Active Beam‐Reconfigurable Retrodirective Array
Nanophotonics, Volume 15, Issue 13, 13 July 2026.The proposed beam‐reconfigurable retrodirective array not only enables retroreflection toward the signal source but also achieves flexible beam steering via a tunable reflection plate, offering a viable solution for real‐time multipoint communication and multitarget wireless power transfer.

Fundamental aspects of netted radar performance [PDF]
, 2010 Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...

MODELING OF BISTATIC RADAR CLUTTER
Perner’s Contacts, 2012 The bistatic radar forms a basic part of multistatic radar systems for Air Traffic Control. The effort in this article is to provide the inside and make basis for future research of the bistatic radar clutter.
