Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is considered as a problem of a great importance. Nowadays, however, microwave technique for localized testing biological ...

We are developing a reflective metal-insulator-metal (MIM) filter with narrow band absorption. In the MIM structure, the interaction between subwavelength multilayer and visible light, and the resultant surface plasmon resonance (SPR) in specific illumination conditions must be understood. Such electromagnetic field interactions have been analysed using COMSOL Multiphysics and RF Module.

This work presents an alternative method for curing cork stoppers based on microwave radiation, which is energetically more efficient, where it is possible to accelerate the reaction rate and therefore reduce the cure time comparatively with conventional curing methods. The microwave energy is directly introduced in the volume of the dielectric material and as a consequence, the quality of the ...
Self-Consistent Modeling of Thin Conducting Wires and Their Interaction with the Surrounding Electromagnetic Field
ABB AB, Corporate Research, Västerås, Sweden
It is demonstrated how the RF Module of COMSOL Multiphysics® can be used to approximately model thin conducting wires or cables and how they interact with a surrounding electromagnetic field. Despite being non-stringent the method can reasonably well predict currents induced by an applied electromagnetic field in wires, and networks of wires, as well as fields radiated from current-carrying ...

In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the disturbing signal inside the system, which is necessary for the following simulation, will be described ...

The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at 2.45 GHz for a standard wave guide and a concrete block. The temperature field is obtained with the heat ...

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase chemical species) and fluid (auxiliary air) phases. In this way the heat and mass fluxes vary seamlessly ...

Negative Refractive Lens (NRL) has shown that an optical system can produce images with details below the classic Abbe diffraction limit. This optical system transmits the electromagnetic fields, emitted by an object plane, towards an image plane producing the same field distribution in both planes. Recently, two devices with positive refraction, the Maxwell Fish Eye lens (MFE) (Leonhardt et al. ...

Influence of chiral objects on spontaneous emission of atoms and molecules is under attention nowadays. The problem of interaction of chiral molecules with one  or two chiral  spheres was solved analytically recently by our group. The analytical results however are very difficult and needed to be calculated carefully. We modify the RF Module of COMSOL Multiphysics® in order to simulate ...
