Mapping the seafloor in the deep ocean is currently performed using sonar systems on surface vessels (low-resolution maps) or undersea vessels (high-resolution maps). Surface-based mapping can cover a much wider search area and is not burdened by the

At terahertz frequencies, link discovery by scanning is impractically slow. Here, the authors propose an alternative, single-shot link-finding method based on a leaky-wave device.

Many popular numerical methods, such as finite difference and spectral methods, rely on simple domain geometry and environmental smoothness. Unfortunately, these features are rarely found in real-world simulations. We propose learning coordinate tran

In weakly scattering media, the parabolic wave equation is often utilized to develop approximate solutions to the Helmholtz equation. However, in three dimensions, at high frequencies, and when the computational domain becomes very large, computation

The vast size of the ocean coupled with the Nyquist criterion often makes high-frequency ocean acoustics computationally intractable without approximation. A common approach is to employ ray theory to develop an approximate Green’s function for the

The spatial profile of a beam can experience complicated reshaping after interacting with a planar resonator near resonant conditions. Previously, this phenomenon was recognized as the Goos–Hanchen effect, which only partially explains the experime

Accurately characterizing the width of a narrow (high Q) resonance can be quite challenging, requiring either a high-resolution grating spectrometer or a Fourier transform spectrometer with a long delay range. Here, we describe a new technique to det
