A nested hybridizable discontinuous Galerkin method for computing second-harmonic generation in three-dimensional metallic nanostructures

, 2020
In this paper, we develop a nested hybridizable discontinuous Galerkin (HDG) method to numerically solve the Maxwell's equations coupled with the hydrodynamic model for the conduction-band electrons in metals.

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

IEEE 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.

Two-photon exchange and electromagnetic proton form factors [PDF]

Nuclear Physics A, 2005
The presence of $2 $-exchange in electron proton elastic scattering is discussed. From C-invariance and crossing symmetry, $2 $ contribution induces a specific dependence of the reduced cross section on the variable $ $. No evidence of such dependence exists in the available experimental data.

Negative Refraction and Left-Handed Electromagnetism in Microwave Photonic Crystals [PDF]

Physical Review Letters, 2004
We demonstrate negative refraction of microwaves in metallic photonic crystals. The spectral response of the photonic crystal, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical simulations. The negative refraction observed corresponds to left-handed electromagnetism and arises

Giant Asymmetric Radiation from an Ultrathin Bianisotropic Metamaterial

, 2018
Unidirectional radiation is of particular interest in high-power lasing and optics. Commonly, however, it is difficult to achieve a unidirectional profile in such a system without breaking reciprocity.

Comparative Modeling of Infrared Fiber Lasers

Photonics, 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.
