In this paper, the attempt has been made to design and analyze single strip shielded Microstrip line with capacitive coupling. The main objective is to compute the capacitance per unit length of shielded Microstrip line using Finite Element technique. The computational and simulation ... En savoir plus
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 ...

The evaluation of defect size and nature are two most controversial topics in ultrasonic flaw detection. The operation consists of an application of ultrasonic waves to pipes in order to detect metal loss and other defects in the pipe wall due to corrosion and other degradation ... En savoir plus
The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation ... En savoir plus
A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. En savoir plus
The design of a magnetic resonance imaging (MRI) RF coil using finite element method-based analysis is an essential part of a multi-year research project at the National Institute of Standards and Technology, Gaithersburg, Maryland, where the goal of the project is to develop a “phantom” ...

This paper analyzes the magnetic behavior of electroplated wires. For this purpose the resistance and inductance of single turn loops and coils have been simulated and measured. The measurement is delicate due to the influence of a stray capacitance. We show that the quality factor of ... En savoir plus
The optimized design of a waveguide applicator has been proposed for superficial microwave hyperthermia using COMSOL Multiphysics 3.5a. In microwave hyperthermia cancer treatment body tissue is exposed to high temperatures using external and internal heating devices. Non-Invasive or ... En savoir plus
In this session, we will discuss and showcase a few examples of advanced acoustics applications. In this context, “advanced” means problems that cannot simply be modeled “out-of-the-box,” but require the flexibility and strengths of COMSOL Multiphysics® software. Topics include: • ... En savoir plus
