Changes

Like every other electromagnetic solver, [[EM.Cube]]Terrano's SBR ray tracer requires a source for excitation and one or more observables for generation of simulation data. [[EM.Cube]]'s new [[Propagation Module]] Terrano offers several types of sources and observables for a SBR simulation. You can mix and match different source types and observable types depending on the requirements of your modeling problem. There are two types of sources:

* [[#Defining Receiver Sets|ReceiversReceiver]]

* Far FieldsField Radiation Pattern

The simplest SBR simulation can be performed using a short dipole source with a specified field sensor plane. In this wayAs an asymptotic EM solver, [[EM.Cube]] 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 a more realistic communication link. A &quot;classic&quot; conventional urban propagation scene can be set up using a &quot;Transmitter&quot; transmitter source and an array of &quot;Receiver&quot; observables. A transmitter is a point radiator with a user defined radiation pattern. A receiver is a polarization-matched isotropic point radiator that collects the received rays at its aperture. Using receivers, you can calculate the received power coverage map of your propagation scene. You can also calculate your channel's path loss between the transmitter and all the receivers. <br />
