This work presents the study of spiral RF MEMS switch which has low actuation voltage due to spiral structure. This work is inspired by the superior performance of electrostatic RF MEMS switches over the conventional state-of-the-art solid-state devices and the potential applications in communication field. The customary high actuation voltage limits the reliability and applications especially ...

The modelling of a ferrite material is conventionally carried out using the Polder permeability tensor which assumes that the ferrite is saturated by a uniform magnetic field. This assumption is often inaccurate due to the constraints imposed by boundary conditions which renders the magnetic field non-uniform. This work proposes to overcome this by determining the magnetic field through a ...

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 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 ...

The electromagnetic fields have a great influence on the behavior of all the living systems. The human body itself is a source of naturally generated electric and magnetic fields. When external signals of comparable strength flows through the human body; the nature of changes that such signals could induce in natural electrochemical processes and voltage is a subject of interest and of ...

Industrial microwave ovens are widely used in agri-food and chemical applications. Resonant cavities are used to speed up chemical reactions and have the advantage to be small sized and efficient in terms of microwave distribution. These multimode cavities are considered as batch ovens where a small amount of products is treated. Rotating plates are added in the cavities to ensure a homogeneous ...

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.

Ubiquitous, unobtrusive wearable computing has tremendous potential for impacting many applications including medical, personal entertainment and surveillance. Advances in the underlying technology have allowed for consistent reduction in the size and weight of emerging solutions, with increasing subsystem integration. A key component for the realisation of these systems is the short and long ...
