Ray tracing propagation model - MATLAB
https://www.mathworks.com/help/comm/ref/rfprop.raytracing.html
Create a ray tracing model. Use the image method and calculate paths with up to one reflection. Then, display the propagation paths. pm = propagationModel ( "raytracing", "Method", "image", ... "MaxNumReflections" ,1); raytrace (tx,rx,pm) For this ray tracing model, there is one propagation path from the transmitter to the receiver.

The ray-tracing consists now of launching a image ray in the depth model under a 90 degree kick-off angle at the surface. The distance travelled in layer 1 is given by the OWT to the interface 1 at the CMP position on the stack. Snell's Law is applied and the ray is continued in medium 2.

Ray Tracing for Radio Propagation Modeling: Principles …
https://ieeexplore.ieee.org/document/7152831
This paper reviews the basic concepts of rays, ray tracing algorithms, and radio propagation modeling using ray tracing methods. We focus on the fundamental concepts and the development of practical ray tracing algorithms. The most recent progress and a future perspective of ray tracing are also discussed. We envision propagation modeling in the near …
Ray Tracing for Wireless Communications - MATLAB

The ray tracing model incorporates building and surface materials into the propagation loss calculations by using the complex relative permittivity of the surface, εr. The ITU-R P.2040-1 [5] and ITU-R P.527 [6] recommendations include methods, equations, and values used to calculate εr for a range of frequencies. The equations for εr are:
13.016 Introduction to Geometric Modeling and Computation
http://deslab.mit.edu/DesignLab/courses/13.016/graphics/ray-tracing.html
Ray tracing is a technique used for generating highly realistic images. light and can correctly handle such visual artifacts as shadows, reflection, and refraction. Ray tracing reverses the traditional rendering process. projecting each vertex of …
Ray-Tracing: Generating Camera Rays (Definition of a Ray)
https://www.scratchapixel.com/lessons/3d-basic-rendering/ray-tracing-generating-camera-rays
Ray-tracing is a technique used to compute the visibility between points. It is simply a technique based on the concept of ray which can be mathematically (and in a computer program) defined as a point (the origin of the ray in space) and a direction.
Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
Optical ray tracing describes a method for producing visual images constructed in 3D computer graphics environments, with more photorealism than either ray casting or scanline rendering techniques. It works by tracing a path from an imaginary eye through each pixel in a virtual screen, and calculating the color of the object visible through it.

[ 1] [ 3] Ray tracing models are extensively used in software propagation prediction packages, which justifies a closer look at them in this section. 3.3.1 Ray Tracing Notations Rays are an optical approximation of the electromagnetic wave; as seen earlier, in free space it is convenient to focus on the propagation of the electric field.
