Dielectric Resonator Reflectarray as High-Efficiency Nonuniform Terahertz Metasurface

Advances in terahertz technology rely on the combination of novel materials and designs. As new devices are demonstrated to address the terahertz gap, the ability to perform high-efficiency beam control will be integral to making terahertz radiation a prac ...

Exploiting the leaky-wave properties of transmission-line metamaterials for single-microphone direction finding

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

A transmission-line acoustic metamaterial is an engineered, periodic arrangement of relatively small unit-cells, the acoustic properties of which can be manipulated to achieve anomalous physical behaviours. These exotic properties open the door to practica ...

Far-field coupling in nanobeam photonic crystal cavities

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Ian Michael Rousseau, Irene Sánchez Arribas

We optimized the far-field emission pattern of one-dimensional photonic crystal nanobeams by modulating the nanobeam width, forming a sidewall Bragg cross-grating far-field coupler. By setting the period of the cross-grating to twice the photonic crystal p ...

Quantitative and Direct Near-Field Analysis of Plasmonic-Induced Transparency and the Observation of a Plasmonic Breathing Mode

Klaus Kern, Moritz Esslinger

We investigated experimentally and numerically in the optical near-field a plasmonic model system similar to a dolmen-type structure for phenomena such as plasmon-induced transparency. Through engineering of coupling strength, structure orientation, and in ...

Analysis and Design of Mobile Device Antenna-Speaker Integration for Optimum Over-the-Air Performance

Juan Ramon Mosig, Nicolas Chavannes

In this paper, the mutual coupling between a mobile device antenna and a closely integrated miniature moving-coil speaker is investigated. The analysis focuses on the speaker radio-frequency harmonic resonance characteristics and the antenna radiation effi ...

Optical Design of Multisource High-Flux Solar Simulators

Sophia Haussener

We present a systematic approach to the design of a set of high-flux solar simulators (HFSSs) for solar thermal, thermochemical, and materials research. The generic simulator concept consists of an array of identical radiation modules arranged in concentri ...

The Sommerfeld Halfspace Problem Redux: Alternative Field Representations, Role of Zenneck and Surface Plasmon Waves

Juan Ramon Mosig, Krzysztof Michalski

The problem of a vertical Hertzian dipole radiating in the presence of a lossy conducting halfspace, first formally solved by Sommerfeld in 1909, is revisited. Using rigorous operator theory concepts and the characteristic Green function procedure, alterna ...

On the Surface Fields Excited by a Hertzian Dipole Over a Layered Halfspace: From Radio to Optical Wavelengths

Juan Ramon Mosig, Krzysztof Michalski

The Sommerfeld halfspace problem is revisited allowing for multilayer and plasmonic media, with a focus on the surface field computation. Alternative field representations are discussed and an improved Sommerfeld-Norton groundwave formula is developed. The ...

Path-loss and car-body-effect characterization for smart tires communications at UWB and ISM bands

Pierre-André Farine, Cyril Botteron, Christian Robert, Gabriele Tasselli, Saeed Ghamari, Yi Guo

Next generation of smart tires will improve the safety and stability of the vehicle by monitoring road parameters, such as pavement and rolling conditions, with sensors placed on tire surface. Between the tread and the metal belt of the tire there are only ...
