MEMS Module
The design and modeling of microelectromechanical systems (MEMS) is a unique engineering discipline. At small length scales, the design of resonators, gyroscopes, accelerometers, and actuators must consider the effects of several physical phenomena in their operation. Consequently, COMSOL Multiphysics is ideally suited for MEMS applications. To this end, the MEMS Module provides predefined user interfaces with associated modeling tools, referred to as physics interfaces, for a variety of coupled physics, including electromagnetic-structure, thermal-structure, or fluid-structure interactions. You can include a variety of damping phenomena in your model: thin-film gas damping, anisotropic loss-factors for solid and piezo materials, anchor damping, and thermoelastic damping. For elastic vibrations and waves, perfectly matched layers (PMLs) provide state-of-the-art absorption of outgoing elastic energy.

Tailor-Made to Simulate Low-Temperature Plasma Sources and Systems
Plasma Module
The Plasma Module is tailor-made to model and simulate low-temperature plasma sources and systems. Engineers and scientists use it to gain insight into the physics of discharges and gauge the performance of existing or potential designs. The module can perform analysis in all space dimensions 1D, 2D, and 3D. Plasma systems are, by their very nature, complicated systems with a high degree of nonlinearity. Small changes to the electrical input or plasma chemistry can result in significant changes in the discharge characteristics.

Predicting Microwave and RF Designs Virtually
RF Module
The RF Module is used by designers of RF and microwave devices to design antennas, waveguides, filters, circuits, cavities, and metamaterials. By quickly and accurately simulating electromagnetic wave propagation and resonant behavior, engineers are able to compute electromagnetic field distributions, transmission, reflection, impedance, Q-factors, S-parameters, and power dissipation. Simulation offers you the benefits of lower cost combined with the ability to evaluate and predict physical effects that are not directly measurable in experiments.
