== Using EM.Terrano as an Asymptotic Field Solver ==
=== Defining Sources & Observables for Your SBR Simulation ===
Like every other electromagnetic solver, EM.Terrano's SBR ray tracer requires an excitation source and one or more observables for the generation of simulation data. EM.Terrano offers several types of sources and observables for a SBR simulation. You already learned about the transmitter set as a source and the receiver set as an observable. You can mix and match different source types and observable types depending on the requirements of your modeling problem.

{{Note| In order to define either transmitters or receivers, first you have to define base points. For a transmitter, you additionally need to import a radiation pattern file from one of [[EM.Cube]]'s other computational modules.}}
