In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ... 詳細を見る
This example exemplifies how to model the impedance of a waveguide of varying cross sectional area. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Computing the Impedance of a Corrugated Waveguide". 詳細を見る
Manual design optimization typically requires numerous sweeps over a parameterized geometry, but it does not guarantee optimal performance under given conditions. Shape optimization removes the need for explicit parameterization and can achieve comparable or even better performance in a ... 詳細を見る
In this model, the electrical performance of a W-band waveguide to microstrip line transition (WMLT) is investigated. A standard WR10 waveguide is used and the transition from waveguide to microstrip line is achieved by utilizing the longitudinal probe (also known as E-plane probe) ... 詳細を見る
This model demonstrates two ways of modeling waveguides that support multiple modes. A PML can be used to absorb any modes, or Ports can be explicitly added for each possible mode. Learn more in this accompanying blog post: Modeling Waveguides that Support Multiple Modes 詳細を見る
This model is used to demonstrate the solution to a classic brainteaser in electromagnetics. A long loop of wire is connected to a source and a receiver, which are placed 1 meter apart. The objective of the model is to compute how long it takes for the receiver to sense when the source ... 詳細を見る
A circularly polarized GHz wave is incident on a layer of cold magnetized plasma. Depending on the operating frequency and plasma state, the incident wave can excite a set of waves with different polarizations. The resulting reflection and transmission characteristics can be of interest ... 詳細を見る
Cascaded cavity filters provide much better bandpass filter performance than single cavity filters. This example demonstrate how to use shape optimization to optimize three rectangular cavity filters coupled via slots. The calculated S-parameters show excellent out-of-band rejection. 詳細を見る
This example model demonstrates shape optimization of a cavity filter using the Transformation feature, so the boundaries remain flat and angles do not change. The optimization considers both insertion loss and out-of-band rejection. The optimized shape is verified using a different mesh ... 詳細を見る
