Compact grating coupler using asymmetric waveguide scatterers
Ashutosh Patri, Xiao Jia, Muhammad Mohsin +2
We demonstrate a novel grating coupler design based on double asymmetric and vertically oriented waveguide scatterers to efficiently couple normally incident light to a fundamental…
Linear Pulse Compansion using Co-propagating Space-Time Modulation
Nima Chamanara, Christophe Caloz
This paper presents a pulse compansion, i.e. compression or expansion, technique based on co-propagating space-time modulation. An engineered asymmetric space-time modulated medium…
Wave Scattering by a Cylindrical Metasurface Cavity of Arbitrary Cross-Section: Theory and Applications
Mojtaba Dehmollaian, Nima Chamanara, Christophe Caloz
This paper presents a technique, combining the integral equations (IE) and the Generalized Sheet Transition Conditions (GSTCs) with bianisotropic susceptibility tensors, to compute…
Microwave Hilbert Transformer and its Applications in Real-time Analog Processing (RAP)
Xiaoyi Wang, Zoé-Lise Deck-Léger, Lianfeng Zou +2
A microwave Hilbert transformer is introduced as a new component for Real-time Analog Processing (RAP). In contrast to its optical counterpart, that resort to optical fiber grating…
Simultaneous Control of the Spatial and Temporal Spectra of Light with Space-Time Varying Metasurfaces
Nima Chamanara, Yousef Vahabzadeh, Christophe Caloz
This paper presents space-time varying (STV) metasurfaces for simultaneously controlling the spatial and temporal spectra of electromagnetic waves. These metasurfaces transform inc…
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…
