This is a conceptual model illustrating how to couple fluid-structure interaction, heat transfer, and thermal expansion. A bimetallic strip in an air channel is heated so that it bends. After some time, an airflow with an inlet temperature which varies in time is introduced. As a ... En savoir plus
Anti-reflective coatings are frequently used in optical systems to reduce the amount of stray light produced when a beam of light crosses from one medium into another medium with a different refractive index. The simplest example of an anti-reflective coating is a quarter-wavelength ... En savoir plus
A thermoacoustic engine is a device with no moving parts that can generate acoustic energy from temperature gradients within the engine. It uses the relationship between the movement of oscillating air and the temperature changes in the air compressed and expanded by the acoustic waves. ... En savoir plus
A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... En savoir plus
This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen ...

Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... En savoir plus
A waveguide-type structure can be fabricated on a substrate by adding vias between the microstrip line and the ground plane. Such a device will behave as a high-pass filter and is attractive because it is easy to fabricate. A model is set up that shows the S-parameters as a function of ... En savoir plus
Photonic crystal devices are periodic structures of alternating layers of materials with different refractive indices. Waveguides that are confined inside of a photonic crystal can have very sharp low-loss bends, which may enable an increase in integration density of several orders of ... En savoir plus
This model illustrates the refraction of light while passing through an optical prism using s– and p–polarized incident Gaussian beams. The prism boundaries are coated with anti–reflection coatings. It also calculates the reflectance and transmittance to analyze the performance of anti ... En savoir plus
Although initially invented to be used in printers, inkjets have been adopted for other application areas, such as within the life sciences and microelectronics. Simulations can be useful to improve the understanding of the fluid flow and to predict the optimal design of an inkjet for a ... En savoir plus
