A system and method for ray launching in electromagnetic wave propagation modeling. A data-processing system receives a dataset that is representative of a plurality of structures within an environment. The plurality of structures is defined in the dataset as having a plurality of surfaces. The system then partitions each surface in the plurality of surfaces into a plurality of tiles. The system pre-computes whether i) the reference point of each corresponding tile in each plurality of tiles of each surface is visible or not from ii) the reference point of each possible spawning tile in each other plurality of tiles. The system then projects a first set of ray tubes based on the pre-computed visibility. The 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 a plurality of structures within an environment. The plurality of structures is defined in the dataset as having a plurality of surfaces. The system then partitions each surface in the plurality of surfaces into a plurality of tiles. The system pre-computes whether i) the reference point of each corresponding tile in each plurality of tiles of each surface is visible or not from ii) the reference point of each possible spawning tile in each other plurality of tiles. The system then projects a first set of ray tubes based on the pre-computed visibility. The 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.
