定量分析生物颗粒形态的变化可以为疾病诊断提供依据。例如血红细胞形态的变化常常会伴随有相应的血液疾病[1]，细胞的癌变常常伴随有细胞核形态的变化[2]等等。无标记的光学显微成像技术已经可以对生物颗粒的尺度和形状进行直接测量。光声显微成像技术 (PAM) 利用生物颗粒固有的吸光本领，已经可以对单个生物颗粒（如细胞和细胞器）进行成像[3]。最近，光声流式仪(the photoacoustic flow-cytometry)已经实现了对单个生物颗粒进行连续检测[4]。然而，为了在大量的生物颗粒中快速检测生物颗粒的形貌，最好的方法是并非对其进行直接成像，而是采用高频光声显微技术 ...

Generating Simulated Data for Spot Heating/IR Camera Analysis of Coal Slag Surfaces

M. Silva[1], T. Ring[1]
[1]Department of Chemical Engineering, University of Utah, Salt Lake City, UT, USA

For combustion simulations, the wall temperature and heat transfer is an important piece of information. Coal combustion systems typically have walls that are initially a cast ceramic, but, with time, slag is deposited on the surface and coal and soot are incorporated into the slag. It ... Read More

Extraordinary Optical Transmission in Copper-Based Devices at Terahertz Frequencies

S. Almousa [1], J. A. Deibel [1],
[1] Department of Physics, Wright State University, Dayton, OH, USA

While low frequency light is poorly transmitted through an aperture in a conductive thin film, in the phenomenon known as extraordinary optical transmission (EOT), a narrow band of selected frequencies are transmitted when incident on an array of subwavelength periodic apertures where ...

Simulations of Negative Curvature Hollow-core Fiber

J. Zhang[1], Z. Wang[1], J. Chen[1]
[1]College of Optoelectronic Science and Engineering, National University of Defense Technology, Changsha, Hunan, China

COMSOL Multiphysics® software was used to simulate and analyze the transmission attenuation spectra of the negative curvature hollow-core fiber (NCHCF) over the wavelength from 2.7 μm to 4.2 μm. The effect of thickness of capillaries and the effect of the distance between the capillaries ... Read More

COMSOL Multiphysics® Software for Simulation of Surface Response to Excitation Method for Manufacturing Process Performance Monitoring

H. Fekrmandi[1], N. Miniello[1], R. Kiflemariam[1], I. Nur Tansel[1]
[1]Mechanical & Materials Engineering Department, Florida International University, Miami, FL, USA

In this study, COMSOL Multiphysics® software was used to simulate the surface response to excitation method (SuRE). An aluminum beam with a piezoelectric element bonded is modeled using the COMSOL Acoustics Module. A frequency domain sweep study was performed to simulate the sweep sign ... Read More

R. van Tijum
Dr.
Advanced Technology Center, Philips Consumer Lifestyle, Drachten, The Netherlands

Redmer van Tijum studied Applied Physics at the University of Groningen. In 2006, he received his PhD title on ‘Interface and surface roughness of polymer metal laminates’ in the field of Material Science at the University of Groningen. After that he became research and development ... Read More

Design and Simulation of a Piezoelectric Actuated Valveless Micropump

J. J. Rojas [1], J. E. Morales [2],
[1] School of Electromechanical Engineering, Instituto Tecnológico de Costa Rica, Cartago, Costa Rica
[2] School of Electronic Engineering, Instituto Tecnológico de Costa Rica, Cartago, Costa Rica

Microfluidics is a multidisciplinary field, basically it designs systems to handle small volumes of fluids. Most applications require a pumping action in order to move the fluid trough the system. For most of them a micro scale active pump is highly desirable. A piezoelectric micropump ... Read More

Low Cost All Optical Swept Source for Optical Communication Applications

J. T. Andrews[1], S. Chaurasiya[1], O. P. Chaudhary[1], D. Agarwal[1]
[1]National MEMS Design, Department of Applied Physics, Shri G S Institute of Technology & Science, Indore Madhya Pradesh, India

By introducing a periodic modulation in a waveguide, it is possible to create an interaction between forward-traveling and backward-traveling modes of an optical waveguide. Bragg grating may be a one dimensional diffraction grating which diffracts light from the forward-traveling mode ... Read More

Nanoscale Heat Transfer using Phonon Boltzmann Transport Equation

S. Sihn[1,2], and A.K. Roy[2]

[1]Air Force Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio, USA
[2]University of Dayton Research Institute, Dayton, Ohio, USA

COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular ... Read More
