A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... Mehr lesen
The electrostatically tunable parallel plate capacitor in this example is a typical component in various MEMS devices for radio frequencies that range between 300 MHz and 300 GHz. You can modify the distance between the two plates, as the applied voltage changes, through a spring ... Mehr lesen
In this example, a simplified micromechanical model of a unit cell with periodic boundary conditions is analyzed. The homogenized elastic and thermal properties of a composite material are computed based on individual properties of fiber and matrix. A comparison of numerical values are ... Mehr lesen
A typical capacitor is composed of two conductive objects with a dielectric in between them. A voltage difference applied between these objects results in an electric field between them. This electric field exists not just directly between the conductive objects, but extends some ... Mehr lesen
In this example, a rotor supported on two hydrodynamic bearings is analyzed. An eccentric disk located between the two bearings causes the rotor to whirl. One of the bearings is misaligned with the axis of the rotor. The Beam Rotor with Hydrodynamic Bearing interface in the ... Mehr lesen
This tutorial model presents a study of a coaxial DC corona discharge in dry air at atmospheric pressure. The dimensions and operation conditions are similar to ones found in electrostatic precipitators with wire-to-plate configurations. The inner wire electrode has a 100-mm radius and ... Mehr lesen
Dielectric microspheres can support whispering gallery modes with high optical quality factors. This model illustrates how to compute the different eigenmodes and resonance frequencies. The resonance frequencies are either filtered by their spatial localization in the resonator or by ... Mehr lesen
Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... Mehr lesen
Phononic and sonic crystals have generated rising scientific interest for very diverse technological applications. These crystals are made of periodic distributions of scatterers embedded in a matrix. Under certain conditions, acoustic band gaps can form. These are spectral bands where ... Mehr lesen
This model analyzes the thermal expansion in a MEMS device, such as a microgyroscope, where thermal expansion should be minimized. The device is made from the copper-beryllium alloy UNS C17500 and uses temperature-dependent material properties from the Material Library. The purpose of ... Mehr lesen
