Localized Photonic jets from flat 3D dielectric cuboids in the reflection mode

, 2015
A photonic jet (terajet at THz frequencies) commonly denotes a specific spatially localized region in the near-field at the front side of a dielectric particle with diameter comparable with wavelength illuminated with a plane wave from its backside (i.e.,

Fully Integrated Silicone Electromagnetic Actuators for Untethered and Bio‐Inspired Soft Robotics

Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.
GA: A new class of soft electromagnetic actuators, with embedded coils and magnets, is here presented to enhance portability and usability outside structured environments. These actuators, fabricated through a custom additive manufacturing‐assisted process, offer high responsiveness, energy efficiency, and stretchability.

A low‐profile tri‐band shared‐aperture antenna for Sub‐6G wide‐beam and millimetre‐wave high‐gain applications

IET Microwaves, Antennas & Propagation
To achieve multi‐function integration and independent performance regulation of microwave and millimetre‐wave (mm‐Wave) shared‐aperture antennas, a design method based on embedded structure fusion is proposed.

An NSCT-Based Multifrequency GPR Data-Fusion Method for Concealed Damage Detection

Buildings
Ground-penetrating radar (GPR) is widely employed as a non-destructive tool for subsurface detection of transport infrastructures. Typically, data collected by high-frequency antennas offer high resolution but limited penetration depth, whereas data from

Fast Interneuron Dysfunction in Laminar Neural Mass Model Reproduces Alzheimer's Oscillatory Biomarkers

Human Brain Mapping, Volume 47, Issue 1, January 2026.
A computational laminar model links fast interneuron dysfunction to early hyperexcitability and late hypoactivity in Alzheimer's disease, reproducing key M/EEG biomarkers and capturing the disease's biphasic electrophysiological progression. ABSTRACT Early‐stage AD involves cortical hyperexcitability, progressing to oscillatory slowing and hypoactivity.

Probing Viscoelasticity of Polymeric Coatings Using Nonlinear Dynamic Atomic Force Microscopy

Small Methods, Volume 10, Issue 2, 22 January 2026.
For soft materials it is essential to characterize both the elastic and viscous material properties. Using an atomic force microscope, the hardening nonlinearity induced by a tip‐sample contact and bifurcation points can be used to separately estimate the visco‐ and elastic parts of the tip‐sample interaction force.

Target DoA estimation in passive radar using non-uniform linear arrays and multiple frequency channels [PDF]

, 2018
In this paper we present a robust approach for target direction of arrival (DoA) estimation in passive radar that jointly exploits spatial and frequency diversity. Specifically we refer to a DVB-T based passive radar receiver equipped with a linear array
