Variable capacitors between the fF and pF range are very interesting for high frequency applications like variable filters, resonators, etc. For radio astronomy applications variable capacitors, realized by electrostatically actuated, micromechanical Meanders-suspended bridges (MEMS) made of superconducting Niobium, have been measured to find C(V). A non plane capacitance behavior have been ...

In this work, time dependent thermal analyses, performed on the 3D FE model of a multilevel Lab on Chip (LOC) platform are executed in order to gain insight into the temperature distribution within the device. By means of the COMSOL Multiphysics CAD import module, an extremely close 3D reproduction of the actual device, allowing to probe temperatures in those regions where an experimental ...
Modelling and Simulation of Simultaneous Intrinsic Kinetics, Hydrogen Transport and Heat Transfer in Complex Hydride Hydrogen Storage Systems

Institute of Materials Research
In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, modelling and simulation of the hydrogenation in complex hydride tanks is performed using COMSOL, case study is ...

Our Institute at the West Hungarian University is dealing with modelling of heat physical treatments in agricultural (biological) materials. The essential key in order to gain accurate results is to know the driving forces during heat and mass transfers. In case of mass transfer processes the application of moisture gradient as driving force gives false results. Therefore, we use water ...
Designers of electro-optic modulators and related devices often use separate tools to study the optical and electrical portions of the device. The flexibility of COMSOL Multiphysics makes it possible to construct unified models of EO phenomena including realistic waveguide profiles and anisotropic material properties. We demonstrate the use of the RF Module to compute both RF and optical ...

The mechanical simulation and analysis of the cantilever-to-anchor configuration for an out-of-plane structure used in transducer applications is reported. The polymer-based Buckled Cantilever Plate “BCP” structure, gives the ability to orient an active device from a horizontal to a vertical position, once assembled. In this paper we compare four different cantilever-to-anchor configurations: ...
Modeling a Non-Flooding Hybrid Polymer Electrolyte Fuel Cell and Related Diffusion-Migration-Reaction Systems

University of Delaware, Newark, DE, USA
Introduction: Understanding the mass and charge transport behavior of heterogeneous systems that include diffusion, migration, and reaction of ions is important in fuel cells, batteries, and other electrochemical applications. Here, a numerical model for charged species transport and reaction has been developed to simulate the electrochemical behavior of a novel type of “non-flooding” hybrid ...
