Orthogonal Analysis of Space-Time Crystals
Zoé-Lise Deck-Léger, Amir Bahrami, Zhiyu Li +1
This paper presents a space-time-wise orthogonal analysis of space-time crystals. This analysis provides a solution consisting of a pair of explicit parametric equations that resul…
Generalized FDTD Scheme for Moving Electromagnetic Structures with Arbitrary Space-Time Configurations
Amir Bahrami, Zoé-Lise Deck-Léger, Zhiyu Li +1
We present a generalized FDTD scheme to simulate moving electromagnetic structures with arbitrary space-time configurations. This scheme is a local adaptation and 2+1-dimensional e…
Generalized FDTD Scheme for the Simulation of Electromagnetic Scattering in Moving Structures
Zoé-Lise Deck-Léger, Amir Bahrami, Zhiyu Li +1
Electromagnetic scattering in moving structures is a fundamental topic in physics and engineering. Yet, no general numerical solution to related problems has been reported to date.…
Generalized Total Internal Reflection at Dynamic Interfaces
Zhiyu Li, Xikui Ma, Amir Bahrami +2
Recent research developments in the area of spacetime metamaterial structures and systems have raised new questions as to how the physics of fundamental phenomena is altered in the…
Electrodynamics of Accelerated-Modulation Space-Time Metamaterials
Amir Bahrami, Zoé-Lise Deck-Léger, Christophe Caloz
Space-time varying metamaterials based on uniform-velocity modulation have spurred considerable interest over the past decade. We present here the first extensive investigation of…
Wave Scattering in Moving Media across the Subluminal-Interluminal Regimes
Zoé-Lise Deck-Léger, Xuezhi Zheng, Christophe Caloz
This paper extends current knowledge on electromagnetic wave scattering from bounded moving media in several regards. First, it complements the usual dispersion relation of moving…
Spacetime Metamaterials
Christophe Caloz, Zoé-Lise Deck-Léger
This paper presents the authors' vision of the emerging field of spacetime metamaterials in a cohesive and pedagogical perspective. For this purpose, it systematically builds up th…
Optimal stopping via reinforced regression
Denis Belomestny, John Schoenmakers, Vladimir Spokoiny +1
In this note we propose a new approach towards solving numerically optimal stopping problems via reinforced regression based Monte Carlo algorithms. The main idea of the method is…
What is Nonreciprocity?
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper aims at providing a global perspective on electromagnetic nonreciprocity and clarifying confusions that arose in the recent developments of the field. It provides a gene…
What is Nonreciprocity? Part II
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper is the second part of a two-part paper on \emph{Electromagnetic (EM) Nonreciprocity (NR)}. Part~I has defined NR, pointed out that linear NR is a stronger form of NR tha…
New Electromagnetic Modes in Space-Time Modulated Dispersion-Engineered Media
Nima Chamanara, Zoé-Lise Deck-Léger, Christophe Caloz +1
We report on new electromagnetic modes in space-time modulated dispersion-engineered media. These modes exhibit unusual dispersion relation, field profile and scattering properties…
Optical Isolation based on Space-time Engineered Asymmetric Photonic Bandgaps
Nima Chamanara, Sajjad Taravati, Zoé-Lise Deck-Léger +1
Nonreciprocal electromagnetic devices play an important role in modern optical and microwave technologies. Conventional methods for realizing such systems are incompatible with int…
Wave Deflection and Shifted Refocusing in a Medium Modulated by a Superluminal Rectangular Pulse
Zoé-Lise Deck-Léger, Alireza Akbarzadeh, Christophe Caloz
We explore the problem of scattering in a medium modulated by a superluminal rectangular pulse, with the pulse modulation realized through transverse excitations. We solve this pro…
