Comparison of Thermal Detector Arrays for Off-Axis THz Holography and Real-Time THz Imaging

In terahertz (THz) materials science, imaging by scanning prevails when low power THz sources are used. However, the application of array detectors operating with high power THz sources is increasingly reported. We compare the imaging properties of four di ...

Super-Resolution Imaging of a Dielectric Microsphere Is Governed by the Waist of Its Photonic Nanojet

Martinus Gijs, Raphaël Etienne Jean Trouillon, Hui Yang, Gergely Huszka

Dielectric microspheres with appropriate refractive index can image objects with super-resolution, that is, with a precision well beyond the classical diffraction limit. A microsphere is also known to generate upon illumination a photonic nanojet, which is ...

Acoustic carpet cloak based on an ultrathin metasurface

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

An acoustic metasurface carpet cloak based on membrane-capped cavities is proposed and investigated numerically. This design has been chosen for allowing ultrathin geometries, although adapted to airborne sound frequencies in the range of 1 kHz (λ≈30 cm), ...

Electrothermal actuation of vanadium dioxide for tunable capacitors and microwave filters with integrated microheaters

Mihai Adrian Ionescu, Andreas Schueler, Clara-Fausta Moldovan, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Antonio Paone, Luca Petit

We report the fabrication, modeling and characterization of novel microwave tunable capacitors based on the metal-insulator transition (MIT) of Vanadium Dioxide (VO2) as a future replacement solution for microelectromechanical capacitive switches. We prese ...

Maximizing Nonlinear Optical Conversion in Plasmonic Nanoparticles through Ideal Absorption of Light

Olivier Martin, Jérémy Butet, Shourya Dutta Gupta, Kuang-Yu Yang

The optimization of nonlinear optical processes in plasmonic structures is important for the design of efficient nonlinear nanosources of light. Considering the simple case of spherical nanoparticles, we clearly identify the most efficient channel for seco ...

Low frequency terahertz-induced demagnetization in ferromagnetic nickel

Christoph Peter Hauri, Mostafa Shalaby

A laser stimulus at terahertz (THz) frequency is expected to offer superior control over magnetization dynamics compared to an optical pulse, where ultrafast demagnetization is mediated by heat deposition. As a THz field cycle occurs on a timescale similar ...

Solid-gap resonators based on PVDF-TrFE

Mihai Adrian Ionescu, Mariazel de la Candelas Maqueda López, Wolfgang Amadeus Vitale, Emanuele Andrea Casu

High frequency wine-glass mode bulk MEMS resonators actuated by means of capacitive transduction have been fabricated by using solid-gaps based on polyvinylidenefluoride-trifluoroethylene (PVDF-TrFE). The fabrication process flow of patterned PVDF-TrFE gap ...

Design of tangential viewing phase contrast imaging for turbulence measurements in JT-60SA

Stefano Coda, Kenji Tanaka

A tangential viewing phase contrast imaging system is being designed for the JT-60SA tokamak to investigate microturbulence. In order to obtain localized information on the turbulence, a spatial-filtering technique is applied, based on magnetic shearing. T ...
