After the incident light is reflected, I want to obtain the reflectivity or reflection intensity after reflection, and the corresponding angle theta and angle phi of the reflectivity or intensity, and then draw the three-dimensional diagram of the reflected light as shown in the figure, where the x-axis represents the angle theta, the y-axis represents the angle phi, and the z-axis represents the reflectivity or electric field intensity. Previously, the two-dimensional 2d-Z power monitor was normalized by far-field projection to obtain the reflectivity corresponding to each angle theta, as shown in the following figure. I changed the monitor type to 3D, so that it is theoretically possible to obtain the reflectivity of the reflected light at different angles theta and angle phi, and can draw a three-dimensional figure. However, I do not know whether this idea is feasible, and how to extract the three-dimensional data of the 3D monitor for drawing. It seems that the script library of the official website does not draw the script of the three-dimensional map ? The above is my description of the problem, thank you for your reply and answer, look forward to your answer again, thank you.
