WebSources The simulation uses two plane wave sources which allow us to simulate linear, circular, or elliptically polarized light in a single simulation. For example, to create circularly polarized light, set the amplitude of each source to 1. Set a 90 degree phase difference between the two sources. WebAnalytical Farfield Source To model and measure the characteristics of an antenna, it can be useful to import a farfield. This allows for determining the effect of a reflector disk, creating a farfield array using the farfield array tool, or measuring the effectiveness of a receiver antenna.
