In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission ...

We present a Finite Element Method (FEM) to calculate the complex valued k(?) dispersion curves of a photonic crystal slab in presence of both dispersive and lossy materials. In particular the method can be exploited to study plasmonic crystal slabs. We adopt Perfectly Matched Layers (PMLs) in order to truncate the open boundaries of the model, including their related anisotropic permittivity ...

In this paper we want to figure out the development of a capacitive acceleration-sensor system with the FEM-Method. The sensor-system is in the position to detect accelerations in the range of ±20 g. Furthermore the sensor-element contains a printed RF-inductance, which is used for contactless data transfer. On the one hand the simulation of the L-C-oscillating circuit using the RF Module of ...

FMR spectra of the periodic microstructures (one-dimensional magnonic crystals, 1D MCs) were obtained using COMSOL with use partial differential equation interface. Results of these calculations were successfully compared with an experimental data for Damon-Eshbach (DE) and Backward-Volume (BV) geometries. The presented tool allows to analyze periodic structures with various geometries and ...

Electromagnetic waves in the terahertz (THz) region may be useful for non-destructive imaging and biosensing technology. This presentation shows the example of our research aimed at the development of application in the THz region. The result of comparing the FDTD method and COMSOL Multiphysics is demonstrated in the investigation of metamaterial and the photoconductive antenna.
Use of Simulation in the Development of Next-generation Measurement Standards for Radiation Dosimetry

Calibration of field instruments used in radiation treatment clinics is currently traceable to NIST primary standards via protocols involving static, flat-field radiation beams. By contrast, radiation beams prescribed for treating cancer incorporate temporal and spatial modulation strategies in order to maximize dose to the tumor while sparing healthy tissue. Differences in the detector ...
Interaction between Light Wave and Asymmetric Metal/Insulator/Metal (MM) Structure Coupled with Subwavelength Holes at Optical Fiber Apex
Osaka University, Suita, Osaka, Japan
Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of asymmetric metal/insulator/metal (MIM) layers coupled with subwavelength holes. Behavior of surface plasmon ...

The problem under investigation is electrical scale-up of a generic metallurgical process for primary metal production through resistive heating of slag by electric current, typically supplied by an AC three-phase system. Maxwell’s equations are analyzed revealing that the properties of the solution is determined by the parameter (L/δ)^2, where L is the linear size of the system and δ is the ...

An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical imaging and computational fluid dynamics (CFD) in a time dependent study allowed the determination of wall ...
