Abstract: This paper introduces an unconditionally stable alternating-direction implicit finite-difference time-domain (ADI-FDTD) method enhanced with thin-wire and thin-slot models for efficient ...

Surface-emitting terahertz quantum cascade lasers (THz QCLs) are highly promising for applications requiring high-quality far-field beams and controlled beam divergence. However, limited brightness ...

Peruvian featherweight fighter Luis Pajuelo-Revilla was fired from the Ultimate Fighting Championship (UFC) after he admitted to using doping, following multiple test results. "Pajuelo-Revilla tested ...

In recent years, solar energy has received extensive attention as a clean and renewable energy. We present a perfect broadband solar absorber based on tungsten and semiconductor GaAs in this paper.

In the course of evolution, many organisms have developed unique light manipulation strategies that rely on intriguing combinations of a broad range of optical effects generated by materials with ...

With their vanishing optical permittivity, epsilon-near-zero (ENZ) materials are uniquely suited for manipulating light at the nanoscale, enabling breakthroughs in areas like nonlinear optics. However ...

The optical properties of metals arise both from optical excitation of interband transitions and their collective electronic, or plasmon, response. Here, we examine the optical properties of Cu, whose ...
