A mode analysis study is used to find the complex effective indices for a microstructured optical fiber (MOF), consisting of air holes in a silica host. As the effective index is smaller than the refractive index of the silica background material, the modes are leaky. The model ... En savoir plus
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 ... En savoir plus
This model demonstrates how to simulate the propagation of guided waves in a dielectric S-bent optical waveguide. The model demonstrates that the phase approximation, required by the Electromagnetic Waves, Beam Envelopes interface, can be numerically calculated by solving an additional ... En savoir plus
The first model describes the simultaneous flow of two immiscible fluids in porous media - here air displaces water in a multi-step inlet pressure experiment. We solve for the pressure and the degree saturation for the air and water within a representative volume and so track saturation ... En savoir plus

This model shows how to set up rotating machinery simulations using the frozen rotor approximation for modeling centrifugal ... En savoir plus
A Gaussian beam is launched into BK-7 optical glass. The material has an intensity-dependent refractive index. At the center of the beam, the refractive index is the largest. The induced refractive index profile counteracts diffraction and actually focuses the beam. Self-focusing is ... En savoir plus
This tutorial model presents a study showing the transient negative mobility and the negative differential conductivity effects in xenon. The stationary and time dependent Boltzmann equation in the two-term approximation is used to compute the electron energy distribution function. ... En savoir plus
This example illustrates the modeling of ply drop-off in a composite panel. The panel considered for the analysis has three sections–thick, taper, and thin. The thick section plies are divided into the core, top-bottom belts, and dropped plies. The thick section of the panel has sixteen ... En savoir plus
The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... En savoir plus
This model shows how to analyze a tuning fork based piezoelectric rate gyroscope. The reverse piezoelectric effect is used to drive an in-plane tuning fork mode. This mode is coupled to an out of plane mode by the Coriolis force and the resulting out of plane motion is sensed by the ... En savoir plus
