Abstract: A ray path tracing method using a three-dimensional (3D) modeling structure, includes: generating and developing a 3D modeling structure of a glass window and a window frame; setting a ray transmitting point and a ray receiving point at respective positions, and generating a ray from the transmitting point; and forming a path of a transmitted wave ray, passing through the glass window and analyzing a propagation characteristic of the transmitted wave ray.Further, the ray path tracing method includes forming respective paths of the transmitted wave ray, a reflected wave ray, and a diffracted wave ray, and analyzing respective propagation characteristics of the transmitted wave ray, reflected wave ray, and diffracted wave ray; and calculating electric field intensities at the receiving point about all the paths formed between the transmitting point and the receiving point.
