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…
Inverse-designed low-index-contrast structures on silicon photonics platform for vector-matrix multiplication
Vahid Nikkhah, Ali Pirmoradi, Farshid Ashtiani +3
Inverse-designed Silicon photonic metastructures offer an efficient platform to perform analog computations with electromagnetic waves. However, due to computational difficulties,…
Roadmap on structured waves
K. Y. Bliokh, E. Karimi, M. J. Padgett +47
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave.…
Programmable wave-based analog computing machine: a metastructure that designs metastructures
Dimitrios C. Tzarouchis, Brian Edwards, Nader Engheta
The ability to perform mathematical computations using metastructures is an emergent paradigm that carries the potential of wave-based analog computing to the realm of near-speed-o…
Multiple actions of time-resolved short-pulsed metamaterials
Giuseppe Castaldi, Carlo Rizza, Nader Engheta +1
Recently, it has been shown that temporal metamaterials based on impulsive modulations of the constitutive parameters (of duration much smaller than a characteristic electromagneti…
Reconfigurable nonlinear optical element using tunable couplers and inverse-designed structure
Vahid Nikkhah, Mario Junior Mencagli, Nader Engheta
In recent years, wave-based analog computing has been at the center of attention for providing ultra-fast and power-efficient signal processing enabled by wave propagation through…
