The transition matrix, frequently abbreviated as T-matrix, contains the complete information
in a linear approximation of how a spatially localized object scatters an incident field. The T …

Numerical optimization for the inverse design of photonic structures is a tool that is providing
increasingly convincing results—even though the wave nature of problems in photonics …

We demonstrate that including the second viscosity of an electron gas in the hydrodynamic
model allows for highly accurate modeling of the optical response of heavily doped …

Lightsails are a highly promising spacecraft concept that has attracted interest in recent
years due to its potential to travel at near-relativistic speeds. Such speeds, which current …

Deep learning, a subset of artificial intelligence, has considerably improved the capabilities
of machines in several fields. Deep learning is based on the architecture of neural networks …

In conventional homogeneous and isotropic materials light propagation is constrained by
the diffraction limit, which prevents its confinement in volumes with dimensions below about …
