This is a model of an RF waveguide bend with a dielectric block inside. There are electromagnetic losses in the block as well as on the waveguide walls which cause the assembly to heat up over time. The material properties of the block are functions of temperature. The transient thermal ... En savoir plus

A beam splitter is used to split a single beam of light into two. One way of making a splitter is to deposit a thin layer of metal between two glass prisms. The beam is slightly attenuated within the layer, and split into two paths. In this example, the thin metal layer is modeled using ... En savoir plus
A differential line is composed of two transmission lines excited by two out-of-phase signals. This configuration is known to be useful to enhance signal-to-noise ratio. This example shows how to set up the differential microstrip lines using TEM type ports. En savoir plus
