This tutorial presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... 詳細を見る
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 ... 詳細を見る
Superconducting materials have zero resistivity up to a certain critical current density, above which the resistivity increases rapidly. To model such a material, this example uses the Magnetic Field Formulation physics interface. The model was based on a suggestion by Dr. Roberto ... 詳細を見る
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 ... 詳細を見る
This example provides a walkthrough on how to simulate the basic radiated emission of a printed circuit board and its immunity response from outside noise. First, when one of the microstrip lines is excited, the crosstalk to an adjacent printed line and the radiated field, through an ... 詳細を見る
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 ... 詳細を見る

A magnetic brake consists of a permanent magnet, which induces currents in a rotating copper disk. The resulting eddy currents interact with the magnetic flux to produce Lorentz forces and subsequently a braking torque. This 3D problem is solved using a stationary formulation for the ... 詳細を見る
The elastic cantilever beam is one of the elementary structures used in MEMS designs. This model shows the bending of a cantilever beam under an applied electrostatic load. The model solves the deformation of the beam under an applied voltage. 詳細を見る
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] ... 詳細を見る
