=== Investigating Propagation Effects Selectively ===
Â
In a typical SBR ray tracing simulation, EM.Terrano includes all the propagation effects such as direct (LOS) rays, ray reflection and transmission, and edge diffractions. To better understand these effects, [[EM.Cube]] allows you to enable or disable them selectively. This is done from the Ray Tracing Simulation Engine Settings dialog using the provided check boxes.

The figure below shows the receiver power coverage map of the random city scene with a vertically polarized half-wave dipole transmitter located 10m above the ground and a large grid of vertically polarized half-wave dipole receivers placed 1.5m above the ground.
