High-Precision Multidimensional Photosensor Based on Hybrid Optofluidic Microbubble Resonator

Photonic Sensors
Optical microcavities combined with different materials have inspired many kinds of functional photonic devices, such as lasers, memories, and sensors. Among them, optofluidic microbubble resonators with intrinsic micro-channels and high-quality factors (

Electromagnetic energy transport in finite photonic structures

Optics Express, 2014
We have derived, for oblique propagation, an equation relating the averaged energy flux density to energy fluxes arising in the process of scattering by a lossless finite photonic structure. The latter fluxes include those associated with the dispersion relation of the structure, reflection, and interference between the incident and reflected waves. We

Faults Detection in Phased Array: Compressed vs MUSIC Methods

The problem of phased array diagnostics in the near field is addressed. Instead of the standard spatial domain, the data field is collected from a fixed probe during beam steering in the phase domain.

A Binary-switch Controlled Periodic Half-width Leaky-wave Antenna for Fixed Frequency Beam Steering near the Endfire Region

, 2019
A leaky-wave antenna (LWA) with fixed-frequency beam scanning capabilities is presented in this paper. The main structure is a half-width microstrip LWA (HW-MLWA), and the direction of the main beam at a fixed operating frequency is controlled by using a

Electromagnetic simulations of a photonic luminescent solar concentrator

Optics Express, 2012
Luminescent solar concentrators (LSC) are used in photovoltaic applications to concentrate direct and diffuse sunlight without tracking. We employed 2D FDTD simulations to investigate the concept of a photonic LSC (PLSC), where the luminescent material is embedded in a photonic crystal to mitigate the primary losses in LSCs: the escape cone and ...

On the photon–classical electromagnetic field relationship

Annals of the New York Academy of Sciences
Abstract This paper discusses how the two ways in which the wavefunction of a free‐propagating photon can be introduced—starting from the relativistic energy−momentum relationship or based on the electromagnetic field, in particular on Riemann–Silberstein vectors—are not entirely equivalent since they can lead to different ...
