Cylindrical Superlens by a Coordinate Transformation
, 2008 Cylinder-shaped perfect lens deduced from the coordinate transformation method is proposed. The previously reported perfect slab lens is noticed to be a limiting form of the cylindrical lens when the inner radius approaches infinity with respect to the ...

Broadband reflectionless metasheets: Frequency-selective transmission and perfect absorption
, 2015 Energy of propagating electromagnetic waves can be fully absorbed in a thin lossy layer, but only in a narrow frequency band, as follows from the causality principle.

High Sensitivity Refractive Index Sensor by D-Shaped Fibers and Titanium Dioxide Nanofilm
Advances in Condensed Matter Physics, 2018 This paper presents a high sensitivity liquid refractive index (RI) sensor based on lossy mode resonance (LMR) effect. The D-shaped fibers coated with nanosized titanium dioxide (TiO2) thin film as a sensing head were submerged into different refractive ...

Generating entanglement with low Q-factor microcavities
, 2012 We propose a method of generating entanglement using single photons and electron spins in the regime of resonance scattering. The technique involves matching the spontaneous emission rate of the spin dipole transition in bulk dielectric to the modified ...

Quality factor measurements in cavities with mode overlap [PDF]
, 1994 A new method of measuring quality factors in cavities is presented. This method is well suited to measure quality factors in undamped cavities as well as in heavily damped cavities, and in addition this method provides a possibility of separating modes ...

A systemic model for lossy mode resonances (LMRs)
Optics & Laser TechnologyLossy mode resonances (LMRs) have been widely employed for the development of sensors in the last years. However, the theoretical frameworks for LMRs are scarce and difficult to systematize, hampering the development of this technology. In this work, we propose a new systemic model for assessing LMRs in arbitrary waveguide configurations, based solely ...

Fiber-based early diagnosis of venous thromboembolic disease by label-free D-dimer detection
Biosensors and Bioelectronics: X, 2019 D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and reliable method is a key step to ...
