An Experimental 10-Port Microwave System for Brain Stroke Diagnosis—Potentials and Limitations
SensorsMicrowave imaging systems show potential as replacements for commonly used stroke diagnostic systems. We developed and tested a 10-port microwave system on a liquid head phantom with ischemic and hemorrhagic strokes of varying sizes and positions.

Advanced Materials Technologies, EarlyView.Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

Cryogenic Characterization of Microwave Devices
, 2023 Microwave technologies of interest are ubiquitous in the defence and security field, but less obvious is the frequent crossing of microwave technologies with cryogenics: from quantum computers, working presently only with superconducting microwave ...

Advanced Materials Technologies, EarlyView.This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.
