A New Class of Resonant Metasurfaces Based on Highly Subwavelength Metamaterial-Lined Apertures and Metamaterial-Coated Discs
DownloadSpring 2019
This work presents analytical, numerical and experimental studies of a new class of resonant metasurfaces (MTSs), which may also be classified as miniaturized-element frequency selective surfaces (FSSs). The proposed MTS unit cells consist of circular aperture or disc resonators that are made...

Analysis and Design of A New Class of Miniaturized Circular Waveguides Containing Anisotropic Metamaterial Liners
DownloadFall 2016
This work presents the analysis and design of a new class of miniaturized circular waveguides containing anisotropic metamaterial liners, and reveals in detail intriguing and potentially useful propagation and radiation phenomena. An analytical construction of the liner as a homogeneous,...

Anisotropic Geodesic Filter for Speckle Noise Reduction and Edge Preservation in 2D and 3D Echocardiography
DownloadFall 2018
It is a challenge today for medical practitioners and manufacturers to improve ultrasound image quality as the technology has reached its physical limits. Ultrasound images are a great help for non-invasive diagnostics but suffer from a wide variety of artifacts such as shadowing, limited field...

Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Continuum Modelling and Analysis of a Class of One and Two Dimensional Elastic Metamaterials with Local Rotation
DownloadFall 2022
The group of materials classified as "metamaterials" have accrued great interest in the scientific community as of late for their potential to revolutionize several multidisciplinary applications. Metamaterials are defined as synthetic/man-made materials which have been engineered to possess a...

Control of boundary slip by interfacial nanobubbles: A perspective from molecular dynamics simulations
Download2023-01-01
Ynag, Haichang, Zeng, Binglin, Zhang, Xuehua, Xing, Yaowen, Gui, Xiahui, Cao, Yijun
Enhancing boundary slip using interfacial nanobubbles (INBs) has gained significant interest in nanofluidic transport. In this study, we conducted a comprehensive investigation on the influence of INBs on boundary conditions for both smooth and rough substrates using molecular dynamics...

Fall 2017
Since the development of the fluctuation dissipation theorem for electromagnetics in 1956 by Landau, Lipschitz and Rytov, field correlations have gradually come to be understood as a consistent framework for treating all optical aspects of linear response. In turn, the theory of electromagnetic...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...
