Spatiotemporal cascading of dielectric waveguides
Victor Pacheco-Peña, Nader Engheta
Photonic time interfaces, as the temporal analogue of spatial interfaces between two media, consist of a rapid change of the electromagnetic properties of a material (such as permi…
Temporal chirp, temporal lensing and temporal routing via space-time interfaces
Victor Pacheco-Peña, Mathias Fink, Nader Engheta
A time interface (a rapid change of the constitutive parameters of a material in time), applied within an unbounded medium where a wave travels, can enable frequency conversion, an…
Perfect Splitting in Rectangular Waveguide Junctions for Analogue Computing
William Rogers, Christian Johnson-Richards, Alex Yakovlev +1
It has been recently shown how computing operations such as high-speed switching, routing, and solving partial differential equations can be performed by exploiting perfect splitti…
Plasmonic sensing using Babinet's principle
Joseph Arnold Riley, Michal Horák, Vlastimil Křápek +2
Developing methods to sense local variations in nearby materials, such as their refractive index and thickness, is important in different fields including chemistry and biomedical…
Holding and amplifying electromagnetic waves with temporal non-Foster metastructures
Victor Pacheco-Peña, Yasaman Kiasat, Diego M. Solís +2
We introduce a mechanism that can both hold and amplify electromagnetic waves by rapidly changing the permittivity of the medium during the wave travel from a positive to a dispers…
