An Investigation of Loudspeaker Simulation Efficiency and Accuracy Using i) A Conventional Model, ii) The Near-To-Far-Field Transformation and iii) The Rayleigh Integral

R. Christensen[1], U. Skov[1]
[1] iCapture ApS, Roskilde, Denmark

Simulation on loudspeaker drivers require a conventional fully coupled vibro-acoustic model to capture all effect. An accurate vibroacoustic model can be time-consuming to solve, especially in 3D. In practical applications, this results in poor efficiency concerning the decision-making ... Read More

The Influence of Core Shape and Material Nonlinearities to Corner Losses of Inductive Element

M. Puskarczyk[1], B. Jamieson[1], W. Jurczak[1]
[1]ABB Corporate Research Center, Kraków, Poland

The effects of sharp corners on the flux distribution in a ferromagnetic core are modeled using COMSOL Multiphysics® to determine the time-domain flux density for an applied field which is uniform in the non-corner section of the core. The frequency spectrum of the flux distribution is ... Read More

Impact of a 3D EM Model Configuration on the Direct Optimization of Microstrip Structures

Z. Brito-Brito[1], J. E. Rayas-Sánchez[1], J. C. Cervantes-González[2], C. A. López[2]
[1]The Jesuit University of Guadalajara. Dept. of Electronics, Systems and Informatics, Jalisco, México
[2]Intel Guadalajara Design Center, Jalisco, México

The EM optimization of a coarsely discretized model of a microstrip band-pass filter implemented in COMSOL Multiphysics® was realized using two different model configurations. We presented a systematic methodology to find an appropriate 3D EM model configuration on a direct EM ... Read More

Thermal Analysis Of A Sealed Battery Power System Enclosure For Underwater Operations

C. H. King Joel [1]
[1] Temasek Polytechnic, Singapore

COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... Read More

Wireless Power and Communications for Implantable Biosensors

C. Romero[1], M. Mujeeb-U-Rahman[1]
[1]California Institute of Technology, Pasadena, CA, USA

Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely ... Read More

Energy Harvesting from Variation in Blood Pressure through Deformation of Arterial Wall using Electro-magneto-hydrodynamics

A. Pfenniger[1], V.M. Koch[2], A. Stahel[2], and R. Vogel[1]
[1]ARTORG Cardiovascular Engineering, University of Bern, Bern, Switzerland
[2]Bern University of Applied Sciences, Engineering and Information Technology, Biel, Switzerland

The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is ... Read More

Calculating and Observing Opto-Mechanically Induced Surface Acoustic Waves in a Silica Whispering Gallery Microresonator

J. Zehnpfennig
Photonics Research Center
United States Military Academy
West Point, NY

Here we calculate opto-mechanically induced Surface Acoustic Waves upon a silica microresonator using COMSOL. Using conservation of momentum, we show both analytically and numerically that the photonphonon interaction within the resonator cavity causes a moving train of electrodes - a ... Read More

Simulation and Optimization of MEMS Piezoelectric Energy Harvester with a Non-traditional Geometry

S. Sunithamani[1], P. Lakshmi[1], E. E. Flora[1]
[1]Department of EEE, College of Engineering, Anna University, Chennai, India

Piezoelectric energy harvester converts mechanical vibrations into electrical energy via piezoelectric effect. The geometry of the piezoelectric cantilever beam greatly affects its vibration energy harvesting ability [1]. In this paper a MEMS based energy harvester with a non-traditional ... Read More
