This tutorial analyzes the hysteresis of the conductance-gate-voltage (G-Vg) curves of an InAs nanowire FET, using the density-gradient theory to add the effect of quantum confinement to the conventional drift-diffusion formulation, without a large increase of computational costs. The ... 詳細を見る
In nuclear fusion reactors, the conducting fluid, such as the fusion plasma and the liquid metal in the reactor blanket, will interact with the background magnetic field. This phenomenon is referred to as magnetohydrodynamics (MHD). The electromagnetic field and fluid flow are fully ... 詳細を見る
Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model ... 詳細を見る
This example demonstrates how to set up a spatially varying dielectric distribution. Here, a convex lens shape is defined via a known deformation of a rectangular domain. The dielectric distribution is defined on the undeformed, original rectangular domain and is mapped onto the deformed ... 詳細を見る
Capacitively coupled RF discharges can operate in two distinct regimes depending on the discharge power. In the low power regime, known as the alpha regime, the electric field oscillation is responsible to heat and create electrons. In the high power regime, known as gamma regime, the ... 詳細を見る
A bow-tie antenna patterned on a dielectric substrate is optimized by adjusting the length of the arms and the flare angle to reduce the magnitude of S11, reflection coefficient. The two geometric dimensions used as design variables directly control the antenna's size and shape, and also ... 詳細を見る
In this extension of the model Optical Scattering off a Gold Nanosphere, the transmission spectra due to spherical nanoparticles of gold with varying radii dispersed in glass are computed and mapped onto the CIE 1931 and sRGB colorspaces. For a description of this model, see the ... 詳細を見る
This verification model uses the Electromagnetic Waves, Boundary Elements interface to simulate the RCS of perfectly conducting sphere. The simulated result is compared to analytical calculation to verify the accuracy. 詳細を見る
This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. 詳細を見る
This example investigates the electrical and thermal characteristics of a welding argon arc created in a point-to-plane configuration. The discharge is assumed to be in local thermodynamic equilibrium. The electric arc is considered a conductive fluid medium and is modeled using a ... 詳細を見る
