Broadband Coherent Wave Control Through Photonic Collisions at Time Interfaces
Emanuele Galiffi, Gengyu Xu, Shixiong Yin +3
Coherent wave control exploits the interference among multiple waves impinging on a system to suppress or enhance outgoing signals based on their relative phase and amplitude. This…
Surface-Wave Coupling in Double Floquet Sheets Supporting Phased Temporal Wood Anomalies
Ya-Wen Tsai, Yao-Ting Wang, Emanuele Galiffi +2
We investigate symmetry-selective surface-mode excitation in a general periodically time-modulated double-layer system, where the modulation of the two layers has a constant phase…
Photon conservation in trans-luminal metamaterials
J. B. Pendry, E. Galiffi, P. A. Huidobro
Structures which appear to move at or near the velocity of light contain singular points. Energy generated by the motion accumulates at these points into ever-narrowing peaks. In t…
Crossing the light line
J. B. Pendry, P. A. Huidobro, M. G. Silveirinha +1
We ask the question 'what happens to Bloch waves in gratings synthetically moving at near the speed of light?'. First we define a constant refractive index (CRI) model in which Blo…
Temporal Parity-Time Symmetry for Extreme Energy Transformations
Huanan Li, Shixiong Yin, Emanuele Galiffi +1
Temporal interfaces introduced by abrupt switching of the constitutive parameters of unbounded media enable unusual wave phenomena. So far, their explorations have been mostly limi…
Photon localisation and Bloch symmetry breaking in luminal gratings
E. Galiffi, M. G. Silveirinha, P. A. Huidobro +1
In gratings travelling at nearly the velocity of light a symmetry breaking transition is observed between free-flowing fluid-like Bloch waves observed at lower grating velocities a…
