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
An axisymmetric 3D structure such as a conical horn antenna can be simulated in a fast and efficient way using only its 2D layout. In this model, the antenna radiation and matching characteristics are computed very quickly with respect to the dominant TE mode from the given circular ... Mehr lesen
Chemical vapor deposition (CVD) is a process often used in the semiconductor industry to grow layers of high-purity solid material on top of a wafer substrate. CVD is achieved using many different techniques and across a range of pressures from atmospheric to ultrahigh vacuum (UHV/CVD). ... Mehr lesen
Dieses Modell beschreibt das Verhalten einer Lithium-Ionen-Akku-Einheitszelle, die anhand einer idealisierten dreidimensionalen Geometrie modelliert wird. Die Geometrie ahmt die strukturellen Details in den porösen Elektroden nach. Solche Modelle werden als heterogene Modelle ... Mehr lesen
Magnetic prospecting is a geological exploration method that is applicable to certain types of iron ore deposits, in particular those made up of magnetite and hematite. The method consists of measuring the magnetic anomalies (changes in the earth's magnetic field) due to the presence of ... Mehr lesen
The example Stiffness Analysis of a Communication Mast’s Diagonal Mounting in the COMSOL Multiphysics Model Library shows how you can modify a 3D CAD model to improve its performance. In that case, the applied changes were based solely on the analyst’s experience with similar structures. ... Mehr lesen
The model utilizes a dedicated mesh refinement study, Frequency Domain RF Adaptive Mesh, which dynamically refines the mesh in the region of interest. For the Application Library model Microstrip Patch Antenna, it increases the mesh resolution around areas with high field variations. The ... Mehr lesen
This example models flow in a microchannel heat exchanger by coupling a Laminar Flow interface in 3D to a Pipe Flow interface. By the use of the Pipe Flow interface to model the flow in the microchannels the problem size is significantly reduced. This model showcases the Pipe Connection ... Mehr lesen
Space charge limited emission is a phenomenon that restricts the current of charged particles that can be released from a surface. As the electron current released by a cathode increases, so does the magnitude of the charge density in the immediate vicinity of the cathode. This ... Mehr lesen
