At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... Mehr lesen
Magnetotellurics is a method for estimating the resistivity profile of the Earth's subsurface using the natural electromagnetic source provided by the ionosphere. This model was defined by Zhdanov et al. in a study published in 1997. In this article, various scientific groups compared ... Mehr lesen
This example is an adaptation of our DC Characteristics of a MOS Transistor (MOSFET) model where the metal and dielectric domains are modeled explicitly and not via a boundary condition. Therefore, the potential profile inside the metal and the insulator can be observed. Mehr lesen
This example demonstrates how to use a parameterized slice plot and animation functionality to export a sequence of images. In addition, the example shows how to use a job sequence to perform a programmatic sequence of operations where the model is first solved and then the image ... Mehr lesen
In diesem Tutorial wird das Schwingungsverhalten einer kleinen Aluminiumplatte mit vier Wellenleiterstrukturen analysiert. Dies ist ein Beispiel für eine strukturelle Komponente, die sich in einem Gerät befindet, in dem sich elastische Wellen ausbreiten, wie zum Beispiel ein ... Mehr lesen
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 ... Mehr lesen
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... Mehr lesen
Focusing a laser beam onto the tip of a single mode fiber is a common way to couple light. To achieve good coupling efficiency, the spatial mode of the light field has to match the spatial mode of the fiber. In this model, we use the beam envelope method to compute a small free-space ... Mehr lesen
Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... Mehr lesen
An antenna balun blocks undesirable currents on the outside of a cable. A quarter-wave coaxial balun (1:1) is one of the easiest designs: it works as a transformer and makes the input impedance from the inner conductor to the outer conductor infinite. This model simulates an antenna ... Mehr lesen
