A HIGH-ACCURACY METHOD OF COMPUTATION OF X-RAY WAVES PROPAGATION THROUGH AN OPTICAL SYSTEM CONSISTING OF MANY LENSES

open access: yesTASK Quarterly, 2016
The propagation of X-ray waves through an optical system consisting of many X-ray refractive lenses is considered. Two differential equations are contemplated for solving the problem for electromagnetic wave propagation: first – an equation for the ...

Switchable Polarization Selective Terahertz Wavefront Manipulation in a Graphene Metasurface

open access: yesIEEE Photonics Journal, 2019
We propose a graphene-based metasurface to investigate the function of switchable polarization selective wave manipulation in THz regime by using the finite-difference time-domain method. The proposed metasurface consists of two layers of graphene arrays,

Computation focusing [PDF]

open access: yesProceedings of the ACM on Programming Languages, 2020
Focusing is a technique from proof theory that exploits type information to prune inessential nondeterminism from proof search procedures. Viewed through the lens of the Curry-Howard correspondence, a focused typing derivation yields terms in normal form.
