The 2024 Magnonics Roadmap

Dirk Grundler, Thomas Yu, Ping Che, Qi Wang, Wei Zhang, Benedetta Flebus

Magnonics is a research field that has gained an increasing interest in both the fundamental and applied sciences in recent years. This field aims to explore and functionalize collective spin excitations in magnetically ordered materials for modern informa ...

Inflight Microwave Drying Process of Micro-droplets for High Resolution 3D printing

Kwanghoon Choi

A new Additive-Manufacturing (AM) or 3D printing concept is proposed to improve the printing resolution for metal additive manufacturing in the frame of the SFA-AM project, Powder Focusing for Beam-Induced Laser 3D Printing. The project aims to transport s ...

Magnonic crystals with reconfigurable magnetic defects for spin-based microwave electronics

Korbinian Baumgärtl

Collective spin excitations can propagate in magnetically ordered materials in the form of waves. These so-called spin waves (SWs) or magnons are promising for low-power beyond-CMOS information processing, which does not rely anymore on the lossy movement ...

High-Throughput Nanocapillary Filling Enabled by Microwave Radiation for Scanning Ion Conductance Microscopy Imaging

Aleksandra Radenovic, Georg Fantner, Vytautas Navikas, Sanjin Marion, Sebastian James Davis, Samuel Mendes Leitão

Solid state nanopores provide a highly sensitive tool for single-molecule sensing and probing nanofluidic effects in solutions. Glass nanopipettes are a cheap and robust type of solid-state nanopore produced from pulling glass capillaries with opening orif ...

Electron Spin Resonance detectors from 400 MHz to 360 GHz

Alessandro Valentino Matheoud

Methods based on the electron spin resonance (ESR) phenomenon are non-invasive tools adopted to investigate paramagnetic systems at temperatures ranging from above 1000 K to below 1 K. Since 2008, the group of Dr. Boero has been working on a detection tech ...

EPFL2019

This communication presents the design and measurement results of aperture-coupled stripline-fed wideband patch antennas for nanosatellite applications. The low-profile requirements lead to a strong back radiation from the coupling aperture. Instead of sup ...

Optically isolated millimeter-wave detector for the Toroidal Plasma Experiment

Timothy Goodman, Stefano Alberti, Anja Skrivervik, Ivo Furno, Marcelo Baquero Ruiz, Gennady Plyushchev, Oulfa Chellaï, Fabian Manke

We have designed and built an optically isolated millimeter-wave detection system to prevent interference from a nearby, powerful, 2.45 GHz microwave source in millimeter-wave propagation experiments in the TORoroidal Plasma EXperiment (TORPEX). A series o ...
