Diffraction by a finite parallel‐plate waveguide cavity with perfect electric conductor loading: The case of E polarisation

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
The diffraction by a finite parallel‐plate waveguide cavity with perfect electric conductor loading is rigorously analysed for the E‐polarised case using the Wiener–Hopf technique. Numerical computations of the radar cross‐section have been performed for different physical parameters, providing a detailed analysis of the scattering characteristics ...

Skew Incidence on Concave Wedge With Anisotropic Surface Impedance [PDF]

, 2012
The diffraction of a plane wave at skew incidence by an arbitrary-angled concave wedge with anisotropic impedance faces is studied. Concave wedges are of interest in wireless propagation models, in particular on modeling buildings and reflectors.

Exact Fermi-edge singularity exponent in a Luttinger liquid

, 1997
We report the exact calculation of the Fermi-edge singularity exponent for correlated electrons in one dimension (Luttinger liquid). Focusing on the special interaction parameter g=1/2, the asymptotic long-time behavior can be obtained using the Wiener ...

Singular Integral Equations of Convolution Type With Carleman Shift

Abstract and Applied Analysis, Volume 2025, Issue 1, 2025.
This article discusses a few different types of singular integral equations of the convolution type with Carleman shift in class {0}. By using the theory of Fourier analysis, these equations under consideration are transformed into Riemann–Hilbert boundary value problems for analytic functions with shift and discontinuous coefficients.

Distributed Control for Mittag–Leffler Synchronization of Variable‐Order Fractional Gierer–Meinhardt Reaction‐Diffusion Systems

Journal of Mathematics, Volume 2025, Issue 1, 2025.
This paper investigates Mittag–Leffler synchronization (MLSY) for variable‐order fractional Gierer–Meinhardt reaction‐diffusion systems (VFO‐GM‐RDs). We introduce, for the first time, a distributed control scheme specifically designed to achieve MLSY in these complex systems. A key contribution is the derivation of an explicit analytical expression for

Mechanical loading reveals an intrinsic cardiomyocyte stiffness contribution to diastolic dysfunction in murine cardiometabolic disease

The Journal of Physiology, Volume 602, Issue 24, Page 6705-6727, 15 December 2024.
Abstract figure legend Understanding cardiomyocyte stiffness components is an important priority for identifying new therapeutics for diastolic dysfunction, a key feature of cardiometabolic disease. In this study cardiac function was measured in vivo (echocardiography) for mice fed a high‐fat/sugar diet (HFSD, ≥25 weeks). Performance of intact isolated
