Approaching soft X-ray wavelengths in nanomagnet-based microwave technology

Nature Communications, 2016
Integrating spin waves with microwave circuits is promising for microwave nanoelectronics. Here, Yu et al. demonstrate a reconfigurable microwave-to-magnon transducer by covering yttrium iron garnet with small arrays of tailored magnetic nanodisks, which

A Radar Echo Simulator for the Synthesis of Randomized Training Data Sets in the Context of AI-Based Applications

Sensors
Supervised machine learning algorithms usually require huge labeled data sets to produce sufficiently good results. For many applications, these data sets are still not available today, and the reasons for this can be manifold. As a solution, the missing

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

PHEMT transistor models for accurate CAD of MMIC amplifier

Journal of Telecommunications and Information Technology, 2002
Accurate modeling of microwave monolithic integrated circuits (MMICs) is very desirable for the reason of high fabrication costs of GaAs circuits. Designers are trying to achieve the ``first trial success`` to lower costs and accelerate the introduction
