This model shows how to model an electrolyte-gated organic field-effect transistor based on a general drift-diffusion model. The model uses the Stabilized Convection-Diffusion Equation interface and the Electrostatics interface. The transistor characteristics are visualized. Formation of ... Mehr lesen
This model demonstrates how to design a beam without low Eigenfrequencies by combining the Density Model feature in the Topology Optimization interface with the Stationary Then Eigenfrequency study step. Mehr lesen
Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... Mehr lesen
This model sets up a linear array of nine tonpilz piezoelectric transducers in a 3x3 grid. A voltage is applied that includes a phase change across the three rows. The transducers are located in a box below the sea surface. The exterior acoustics are modeled using the Pressure ... Mehr lesen
A standing contact fatigue test is a procedure used for testing crack growth on the subsurface level. In such a test, a spherical object is pressed against the tested materials and cycled between a high and low compressive load. No translational movement between the two occurs. After a ... Mehr lesen
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Mehr lesen
A Fresnel rhomb is a prism that uses total internal reflection to manipulate the polarization of light. In this example, light in the prism is internally reflected at an angle of incidence that induces a 45-degree phase delay between s- and p-polarized radiation. By subjecting the light ... Mehr lesen
An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... Mehr lesen
A fractal is a mathematical form showing self-repeating patterns. By virtue of its geometrical properties, a fractal structure can generate multiple resonances in RF applications. This antenna model uses a 3rd order Sierpinski triangle and the calculated S-parameters shows good input ... Mehr lesen
This model demonstrates the use of optical tracing for studying optically large gradient-index structures with anisotropic optical properties. Additionally, the model introduces a smoothing technique for handling discontinuities of refractive index on curved surfaces, which are typical ... Mehr lesen
