Ray-tracing methods use discrete rays to represent advancing wavefronts as they propagate from a transmitter through a scene. Rays interact with geometry in the scene through reflections, diffractions, and transmissions. Rays that reach a receiver represent the paths that waves may travel from the transmitter to the receiver. The electric field, received power, and other electromagnetic quantities can be calculated through the superposition of the contributions from all of the propagating waves that reach that receiver point. The two dominant ray-tracing methods are Shooting-and-Bouncing Rays and Image Theory. Remcom’s software combines these two methods to leverage the advantages of each.

JFW’s Model 50PMA-114 is a 5 port transceiver test system operating 30-3000 MHz in a 19 inch rack mount enclosure. There are 10 paths in the 5 port mesh and every path has its own individually controlled programmable attenuator.
