Design of Microwave Resonance Cavity (MRC) to generate non-thermal plasma to treat NOx and SOx from marine diesel engine is presented in this paper. Microwave frequency of 2.45GHz is used generate the required plasma. A number of wave guides are used to transfer the microwave energy into to MRC from the microwave source. COMSOL multi-physics software is used to model the waveguides and to ...

At the Fontys University of Applied Physics (The Netherlands) a plasma etcher has been acquired for educational purposes. The machine operates at low power up to 30 Watt and is driven with a magnetic coil at 13.56 MHz. The use of COMSOL Multiphysics software will be discussed to simulate the temperature and mass fractions of the activated and ionized atoms in the gas. The simulations will be ...

We report the results of simulation showing light coupling in waveguides through prism coupling method. Prism coupling method of light coupling in waveguides is a dominant method adopted by photonic device fabricators. It is necessary to understand the effect various parameters on light coupling in such processes. We used industry standard PDE solver COMSOL Multiphysics to study and analyze the ...

In this study, a computational model is developed and solved using COMSOL Multiphysics software to estimate the lesion size during saline-infused RFA. Transport of saline is set up by modifying the Poisson equation and the convection-diffusion equation  under the Mathematics module. Heating during RFA is set up based on the Joule heating module. To describe the lesion size, the two-state cell ...

Plasmonics is a new branch of the fascinating field of photonics and develops concepts to quench light beyond the diffraction limit and enhance electromagnetic fields. These enhancements occur in metals as localized surface plasmon polaritons (LSP) a coupling of the surface density oscillations of the electron gas to the incident light. With threedimensional nano-structures of coinage metals ...

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate.

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 ...

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 optimization of a low fidelity models. It was confirmed that the direct EM optimization of coarse models in COMSOL could ...

Radiofrequency (RF) tissue ablation is commonly used to treat medical conditions involving dysfunctional tissue especially in the heart, kidneys, lungs, bones, or liver. An electrode at the tip of a catheter delivers high frequency current (350-500 kHz) to the targeted tissue causing it to heat and then ablate without disturbing the electrical signals of the nervous system or heart, and with ...

Surface-enhanced Raman scattering (SERS) is a fingerprint spectroscopy whose sensitivity is down to single molecule level. The mechanism of SERS is mainly contributed to huge enhancement of local electric field, which originated from surface plasmon resonance of metal nanostructures. It is very important to exactly calculate the local enhancement in the electric field strength for right ...
