Goos-Hänchen shifts at a resonance angle of a two-prism structure using COMSOL multiphysics

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2016)

Wenjing Zhang Zhiwei Zhang Peng Yang Xiang Zhu Yifan Dai

We simulated and analyzed Goos–Hänchen (GH) shifts of 633 nm polarized light through a two-prism structure, consisting of a right triangle prism and an isosceles triangle prism with Kretschmann–Raether configuration, by comparing the results from COMSOL Multiphysics (CM) simulation software with that of a stationary-phase analysis (SPA). For this two-prism structure, using a gold film that of thickness 45 nm, the maximum positive GH shift, obtained using SPA at the resonance angle of 44.1°, was 354 μm. Using CM at an incident angle of 43.8°, we found the maximum positive GH shift of 9.45 μm. The results obtained using CM are in agreement with those obtained by the SPA around the resonance angle, although the enhancement effect from CM is much less than that of SPA. This is because SPA depends on the differentiation of the phase shift with respect to the incident angle, while a drastic phase shift occurs at the resonance angle. These results are useful for designing high-sensitivity SPR sensors based on GH shift measurement and for application in waveguide-type SPR devices, with sizes in the order of micro millimeter.

Polynomial preserving recovery for the finite volume element methods under simplex meshes

Mathematics of Computation (2024)

Yonghai Li Peng Yang Zhimin Zhang

The recovered gradient, using the polynomial preserving recovery (PPR), is constructed for the finite volume element method (FVEM) under simplex meshes. Regarding the main results of this paper, there are two aspects. Firstly, we investigate the supercloseness property of the FVEM, specifically examining the quadratic FVEM under tetrahedral meshes. Secondly, we present several guidelines for selecting computing nodes such that the least-squares fitting procedure of the PPR admits a unique solution. Numerical experiments demonstrate that the recovered gradient by the PPR exhibits superconvergence.

Actively tuning of transverse wave band gaps in hybrid sandwich beam metamaterials with shunted piezoelectric array and inertial amplification mechanism

Journal of Intelligent Material Systems and Structures (2022)

Jingru Li Peng Yang Maolong Xia

In this paper, a tunable sandwich beam metamaterial is designed by implementing a hybrid project composed of the piezoelectric shunted array technique and the inertial amplification mechanism. Concerned with the shunted piezoelectric constitutive relation, the kinematic analysis of added mechanism and the transverse motion of base structure, a theoretical model is established to estimate the band gap characteristics of the sandwich beam lined with pyramidal truss cores using the transfer matrix method, whose accuracy is further validated by the finite element simulations. Numerical results show that multiple stop bands are generated at low frequencies owing to the mechanisms of electromechanical resonance, amplifying inertia and mechanical resonance, certainly enhancing the level of vibration suppression. Subsequently, a comprehensive parametric analysis is conducted to investigate the influences of the shunting circuits and attached mechanism on the attenuation diagrams. It is demonstrated that the hybrid sandwich lattice can offer more tunable space to acquire ultra-broad band gaps. Furthermore, based on the design potential, the amplitudes and bandwidths of the attenuation region are maximized by operating an optimization study. Such advanced attenuation performance can be applied for a wide range of engineering applications.
