Design and Analysis of Dual-Polarized Frequency-Selective Metasurface for X-Band Notch Applications [PDF]

open access: yesSensors
This paper presents a miniaturized, polarization-insensitive frequency-selective metasurface (FSMS) with stopband behavior for RF shielding applications. The FSMS is designed to suppress communication at 10 GHz frequency in the X-band.

Stability Criteria and Λ-Fractional Mechanics

open access: yesFractal and Fractional, 2023
Global stability criteria for Λ-fractional Mechanics are established. The fractional extension of a bar under axial loading is discussed. Globally minimizing the total energy function, non-smooth deformations are introduced.

On Λ-fractional visco-elastic beam

open access: yesForces in Mechanics, 2022
Zener's viscoelastic model is studied with the help of the non-local accurate Λ-fractional mathematical analysis. The model has been applied to the general Λ-fractional visco-elastic beam bending.

The Λ-Fractional Hydrocephalus Model

open access: yesAxioms, 2022
Infant hydrocephalus is a clinically abnormal clinical state with an accumulation of fluid in cavities (ventricles) deep within the brain. Hence, pressure is increased inside the skull.

An Improved Version of Residual Power Series Method for Space-Time Fractional Problems

open access: yesAdvances in Mathematical Physics, 2022
The task of present research is to establish an enhanced version of residual power series (RPS) technique for the approximate solutions of linear and nonlinear space-time fractional problems with Dirichlet boundary conditions by introducing new parameter

On Λ-Fractional Wave Propagation in Solids

open access: yesMathematics, 2023
Wave propagation in solids is discussed, based upon inherently non-local Λ-fractional analysis. Following the governing equations of Λ-fractional continuum mechanics, the Λ-fractional wave equations are derived.

Variable λ-Central Morrey Space Estimates for the Fractional Hardy Operators and Commutators

open access: yesJournal of Mathematics, 2022
This paper aims to show that the fractional Hardy operator and its adjoint operator are bounded on central Morrey space with variable exponent. Similar results for their commutators are obtained when the symbol functions belong to λ-central bounded mean ...

On plane Λ-fractional linear elasticity theory

open access: yesTheoretical and Applied Mechanics Letters, 2020
: Non-local plane elasticity problems are discussed in the context of Λ-fractional linear elasticity theory. Adapting the Λ-fractional derivative along with the Λ-fractional space, where geometry and mechanics are valid in the conventional way, non-local

Fractional Type Marcinkiewicz Integral Operator Associated with Θ-Type Generalized Fractional Kernel and Its Commutator on Non-homogeneous Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2022
Let (𝒳, d, μ) be a non-homogeneous metric measure space satisfying the upper doubling and geometrically doubling conditions in the sense of Hytönen. Under assumption that θ and dominating function λ satisfy certain conditions, the authors prove that ...
