Scale-Invariant Waveguiding in Flatland. [PDF]

open access: yesExploration (Beijing)
The study introduces scale‐invariant metasurface waveguides with uniform modal field distribution and an effective index independent of the core width. By leveraging spatial symmetry and fine‐tuning mode profiles, the design is validated through near‐field measurements in the C band, offering potential applications in flat optics, sensing, and ...

A Constructive Method for Approximate Solution to Scalar Wiener-Hopf Equations [PDF]

open access: yes, 2015
This paper presents a novel method of approximating the scalar Wiener-Hopf equation; and therefore constructing an approximate solution. The advantages of this method over the existing methods are reliability and explicit error bounds.

A Novel Approach to Solving Line Source Diffraction Caused by Perfectly Conducting Successive Steps [PDF]

open access: yesJournal of Electromagnetic Engineering and Science
In this study, a new unconventional approach that departs from the classical method is proposed to solve the modified scalar Wiener–Hopf equation of the third kind with regard to the diffraction problem of cylindrical waves caused by perfectly conducting

Majorana edge states in Kitaev chains of the BDI symmetry class

open access: yesSciPost Physics Core, 2023
Majorana edge states in Kitaev chains possessing an effective time reversal symmetry with one fermionic site per unit cell are studied. For a semi-infinite chain the equations for the wave functions of Majorana zero modes can be reduced to a single ...

Wiener-Hopf factorization and distribution of extrema for a family of L\'{e}vy processes [PDF]

open access: yes, 2010
In this paper we introduce a ten-parameter family of L\'{e}vy processes for which we obtain Wiener-Hopf factors and distribution of the supremum process in semi-explicit form. This family allows an arbitrary behavior of small jumps and includes processes

Sliding Window Evaluation of the Wiener-Hopf Equation [PDF]

open access: yesRadioengineering, 2020
This paper presents an efficient method for solving the Wiener-Hopf equation in a sliding window by calculating the correlation matrices recursively. Furthermore, a novel algorithm is introduced for evaluating the inverse of the auto-correlation matrix -

Dynamic Heat Transfer Calculation for Ground-Coupled Floor in Emergency Temporary Housing

open access: yesApplied Sciences, 2022
Generally, ground-coupled floor heat transfer is supposed as annual periodic, which is reasonable for conventional buildings. However, for emergency housing with a short life cycle, the influence of initial soil temperature needs to be considered.
