Advanced Science, Volume 13, Issue 25, 4 May 2026.A large‐aperture, high focusing efficiency and polarization‐independent THz single‐layer achromatic metalens is reported via discrete multi‐wavelength achromatic design and global optimization algorithm. The fabricated metalens exhibits a largest diameter of 2.21 cm, excellent achromatic performance, extremely high average focusing efficiency (> 46 ...

Equations of the Fibre Composite Plates
Engineering Transactions, 1992 The paper is concerned with elastic fibre-composite plates. For the fibre composite the concept of two-phase medium presented in the works of Holnicki-Szulc was used. For the plate the hypothesis of Kirchhoff-Love is applied.

Multigrid Methods for Hellan-Herrmann-Johnson Mixed Method of Kirchhoff Plate Bending Problems
, 2017 A V-cycle multigrid method for the Hellan-Herrmann-Johnson (HHJ) discretization of the Kirchhoff plate bending problems is developed in this paper. It is shown that the contraction number of the V-cycle multigrid HHJ mixed method is bounded away from one

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...

A control volume based formulation of the discrete Kirchoff triangular thin plate bending element [PDF]
, 2009 A control volume method is presented for predicting the displacement and rotation of thin transversely loaded flat plates. The new procedure uses discrete Kirchoff triangle (DKT) elements but introduces a dual mesh of interconnected control volumes (CVs)

Dynamics of thermoelastic thin plates: A comparison of four theories
, 2005 Four distinct theories describing the flexural motion of thermoelastic thin plates are compared. The theories are due to Chadwick, Lagnese and Lions, Simmonds, and Norris.

Exact controllability for systems describing plate vibrations. A perturbation approach
Comptes Rendus. MathématiqueThe aim of this paper is to prove new exact controllability properties of systems described by perturbations of the classical Kirchhoff plate equation. We first consider systems described by an abstract plate equation with a bounded control operator. The

A simple approach to the numerical simulation with trimmed CAD surfaces
, 2015 In this work a novel method for the analysis with trimmed CAD surfaces is presented. The method involves an additional mapping step and the attraction stems from its sim- plicity and ease of implementation into existing Finite Element (FEM) or Boundary ...

Finite-element nonlinear transient response computer programs PLATE 1 and CIVM-PLATE 1 for the analysis of panels subjected to impulse or impact loads [PDF]
Two computer programs are described for predicting the transient large deflection elastic viscoplastic responses of thin single layer, initially flat unstiffened or integrally stiffened, Kirchhoff-Lov ductile metal panels. The PLATE 1 program pertains to
