=== Using EM.Terrano as a Field Solver === The simplest SBR simulation can be performed using a short dipole source with a specified field sensor plane. As an asymptotic EM solver, EM.Terrano then computes the electric and magnetic fields radiated by your dipole source in the presence of your multipath propagation environment. EM.Terrano's short dipole source and field sensor observable are very similar to those of [[EM.Cube]]'s other computational modules. Transmitters and receivers are more complicated source and observables representing You can also compute the far field radiation patterns of a more realistic communication linkdipole in the presence of surrounding scatterers or compute the Huygens surface data for use in [[EM. A conventional urban propagation scene can be set up Cube]]'s other modules. Click here to learn more about using EM.Terrano as a transmitter source and an array of receivers[[Asymptotic Field Solver]].

Transmitters and receivers are more complicated source and observables representing a more realistic communication link. A conventional urban propagation scene can be set up using a transmitter source and an array of receivers. In order to tie up transmitters and receivers with CAD objects in the project workspace, [[EM.Cube]] uses point objects to define transmitters and receivers. These point objects represent the base of the location of transmitters and receivers in the computational domain. Hence, they are grouped together as "Base Sets". You can easily interchange the role of transmitters and receivers in a scene by switching their associated bases. The usefulness of concept of base sets will become apparent later when you place transmitters or receivers on an irregular terrain and adjust their elevation.
