A spherical water-rich load (potato) is placed on the rotating glass tray of a microwave oven some distance from the center of rotation. 1 kW of 2.45 GHz microwave power is applied via a waveguide feed. The plate rotates at 9 degrees per second. The heat transfer model involves the ... Mehr lesen
This model includes a dielectric slab waveguide with a small lossy metallic object nearby. The object causes light to be scattered, absorbed, and both reflected and transmitted along the waveguide. Learn more in this accompanying blog post: Modeling a Scatterer Near an Optical Waveguide Mehr lesen
A dielectric resonator placed near a radiating element can be used to increase directivity and gain. Here, a block of quartz dielectric, with additional passive metallic antenna elements, is placed above a slot antenna. The fields in and around the antenna are solved for. The far field ...

A classic benchmark problem in computational electromagnetics is to solve for the radar cross section (RCS) of a sphere in free space illuminated by a plane wave. This model solves for the RCS of a metallic sphere that has a very high conductivity, which can be treated as a material with ... Mehr lesen
This benchmark model simulates a GaAs nanowire using the self-consistent Schrödinger-Poisson theory to compute the electron density and the confining potential profiles. The predefined Schrödinger-Poisson multiphysics coupling feature is combined with the dedicated Schrödinger-Poisson ... Mehr lesen
Inductive devices experience capacitative coupling between conductors at high frequencies. Modeling this phenomenon requires that you describe electric fields that have components both parallel with and perpendicular to the wire. This consideration might lead to the conclusion that a 3D ... Mehr lesen
This tutorial demonstrates how to build the geometry for the 3D biased resonator from GDS file using the ECAD Import Module and the Design Module. The procedure emulates semiconductor and MEMS fabrication processes to build 3D geometry more efficiently and is more intuitive for those ... Mehr lesen
This model illustrates the process of evaluating the radar cross section (RCS) of a metallic sphere through the utilization of the boundary element method (BEM). By taking advantage of a vertical symmetry plane that is parallel to the polarization of an incident background field, the ... Mehr lesen
This three-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Mehr lesen
This tutorial model analysis of a microstrip patch antenna shows how to couple the finite element method (FEM) to the boundary element method (BEM) for evaluating the field outside the FEM computational domain. The model computes the S-parameter, near-field distribution, and far-field ... Mehr lesen
