Operando monitoring transition dynamics of responsive polymer using optofluidic microcavities

open access: yesLight: Science & Applications, 2021
Operando monitoring transition dynamics of responsive polymer via a self-referencing optofluidic microcavity is demonstrated. The refractive index and temperature information of the analyte during the phase-transition process are precisely decoupled.

Focusing Light with Curved Guided-Mode Resonance Reflectors

open access: yesMicromachines, 2011
Employing numerical simulations, we investigate the possibility of using curved guided-mode resonance (GMR) elements to focus light in reflection. We treat GMR reflectors with a parabolic shape and show that they are capable of focusing light effectively

Electromagnetism with magnetic charge and two photons [PDF]

open access: yesAmerican Journal of Physics, 1996
The Dirac approach to include magnetic charge in Maxwell’s equations places the magnetic charge at the end of a string on which the the fields of the theory develop a singularity. In this paper an alternative formulation of classical electromagnetism with magnetic and electric charge is given by introducing a second pseudo-four-vector potential, Cμ, in

Flexible Design of Broadside-Radiating Linearly-Polarized Edge-Fed Metasurface Antennas

open access: yesIEEE Access
In this work, we design and fabricate broadside-radiating edge-fed metasurface antennas with linear polarization employing a spatially-varying isotropic reactance; in order to avoid losses, the antenna is not terminated on a matched load.

Comparative Modeling of Infrared Fiber Lasers

open access: yesPhotonics, 2018
The modeling and design of fiber lasers facilitate the process of their practical realization. Of particular interest during the last few years is the development of lanthanide ion-doped fiber lasers that operate at wavelengths exceeding 2000 nm.

Photon-photon interactions in cavity electromagnetically induced transparency [PDF]

open access: yesPhysical Review A, 1999
Dissipation-free photon-photon interaction at the single photon level is studied in the context of cavity electromagnetically induced transparency (EIT). For a single multilevel atom exhibiting EIT in the strong cavity-coupling regime, the anharmonicity of the atom-cavity system has an upper bound determined by single atom-photon coupling strength ...

Real-time 3D temperature reconstruction in microwave cancer hyperthermia from scarce temperature measurements

open access: yesNature Communications
Oncological microwave hyperthermia is a clinically proven sensitizer of radio- and chemo-therapies; it acts by selectively increasing the temperature of tumor cells by means of antenna applicators.
