A system and method for ray launching in electromagnetic wave propagation modeling. A data-processing system receives a dataset that is representative of one or more structures within an environment. The system partitions at least a first surface of a first structure into a first plurality of tiles. The system then projects a first set of ray tubes from a predetermined first point within the environment, to the tiles in the first plurality. Each ray tube in the first set is projected to a corresponding tile in the first plurality, based on whether the reference point of the corresponding tile in the first plurality is visible from the transmit point. The data-processing system evaluates the incidence of bounced ray tubes at a predetermined receive point within the environment and then presents a propagation result that is based on the evaluated incidence of the bounced ray tubes.

Abstract

A system and method for ray launching in electromagnetic wave propagation modeling. A data-processing system receives a dataset that is representative of one or more structures within an environment. The system partitions at least a first surface of a first structure into a first plurality of tiles. The system then projects a first set of ray tubes from a predetermined first point within the environment, to the tiles in the first plurality. Each ray tube in the first set is projected to a corresponding tile in the first plurality, based on whether the reference point of the corresponding tile in the first plurality is visible from the transmit point. The data-processing system evaluates the incidence of bounced ray tubes at a predetermined receive point within the environment and then presents a propagation result that is based on the evaluated incidence of the bounced ray tubes.
