“…Time domain methods such as FDTD can handle a variety of large systems as they do not require the solution of a linear system of equations, and can be coupled with other equations, such as the equation for the dynamics of population inversion in a laser. However, they also face some challenges, like the implementation of dispersive materials or periodic boundary conditions for broadband sources at non‐normal incidence . Furthermore, the calculation of radiative fields is not straightforward compared to, for example, the modal methods previously discussed because FDTD assumes a finite window of computation.…”

“…However, they also face some challenges, like the implementation of dispersive materials or periodic boundary conditions for broadband sources at non-normal incidence. [99] Furthermore, the calculation of radiative fields is not straightforward compared to, for example, the modal methods previously discussed because FDTD assumes a finite window of computation. In order to simulate open boundary conditions, PMLs are used; they are built from layers of lossy material with a perfectly matched interface that should not reflect a plane wave for any frequency, angle of incidence, and polarization.…”

Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR) gratings or waveguide‐mode resonant gratings, are dielectric structures where these resonant diffractive elements benefit from lateral leaky guided modes from UV to microwave frequencies in many different configurations. A broad range of optical effects are obtained using RWGs such as waveguide coupling, filtering, focusing, field enhancement and nonlinear effects, magneto‐optical Kerr effect, or electromagnetically induced transparency. Thanks to their high degree of optical tunability (wavelength, phase, polarization, intensity) and the variety of fabrication processes and materials available, RWGs have been implemented in a broad scope of applications in research and industry: refractive index and fluorescence biosensors, solar cells and photodetectors, signal processing, polarizers and wave plates, spectrometers, active tunable filters, mirrors for lasers and optical security features. The aim of this review is to discuss the latest developments in the field including numerical modeling, manufacturing, the physics, and applications of RWGs. Scientists and engineers interested in using RWGs for their application will also find links to the standard tools and references in modeling and fabrication according to their needs.

“…The spectral emissivity can be obtained from Kirchhoff’s law (i.e., ελ=1−Rλfalse), where the reflectance R was calculated by the FDTD. To clarify the angle-dependent behavior, the wideband analysis at oblique incidence was performed by using the FDTD algorithm suggested by Liang et al [18].…”

In this study, a tungsten-SiO2-based metal–insulator–metal-structured metasurface for the thermal emitter of the thermophotovoltaic system was designed and fabricated. The proposed emitter was fabricated by applying the photolithography method. The fabricated emitter has high emissivity in the visible to near-infrared region and shows excellent wavelength selectivity. This spectral emissivity tendency agreed well with the result calculated by the finite-difference time-domain method. Additionally, the underlying mechanism of its emission was scrutinized. Study of the fabrication process and theoretical mechanisms of the emission, clarified in this research, will be fundamental to design the wavelength-selective thermal emitter.

“…In order to investigate the optical properties of the NP distributions, we first calculate the absorption crosssection and near-field response at 532 nm. Calculations were performed with linearly-polarized light at normal and oblique (30°) incidence where the oblique incidence uses the broadband fixed angle source technique [65]. Convergence was obtained for a propagation time of ∼90 fs.…”
