Nonreciprocal reconfigurable microwave optomechanical circuit

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth, Marie Adrienne Ioannou, Akshay Koottandavida

Nonreciprocal devices, such as isolators, are required to protect sensitive superconducting quantum circuits. Growing research has focused on integrated alternatives to the existing bulky ferrite technologies. Here we realize a nonreciprocal isolator with ...

Non-reciprocal magnons in non-centrosymmetric MnSi

Gregory Scott Tucker

Using two cold-neutron triple-axis spectrometers we have succeeded in fully mapping out the field-dependent evolution of the non-reciprocal magnon dispersion relations in all magnetic phases of MnSi. The non-reciprocal nature of the dispersion manifests it ...

Experimental verification of optimal frequency range for microwave head imaging

Jean-Philippe Thiran, Juan Ramon Mosig, Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs

This work presents the experimental verification of the power transmission of a radiating field into the human head for Microwave Imaging (MWI) applications. We aim at finding the range of frequencies that optimize the power scattered by any anomalies from ...

High-Voltage and Low-Leakage AlGaN/GaN Tri-Anode Schottky Diodes With Integrated Tri-Gate Transistors

Elison de Nazareth Matioli, Jun Ma

We present AlGaN/GaN nanostructured Schottky barrier diodes (SBDs) on silicon substrate with high breakdown voltage (V-BR) and low reverse leakage current (I-R), based on a hybrid of tri-anode and tri-gate architectures. The fabricated SBDs presented a sma ...
