Problems solved by technology

[0002] In the field of electromagnetic waves, in order to effectively observe electromagnetic waves, it is often necessary to visualize the electromagnetic wave vector on the surface. However, the traditional field vector visualization only considers the case of a vector field in a single direction, and does not consider the coupling between orthogonal fields. ; It is impossible to dynamically display the fluctuation coupling of electromagnetic waves, and the display speed of electromagnetic wave fluctuations cannot be adjusted, which brings a lot of inconvenience to the dynamic visualization of electromagnetic wave vectors, especially when it comes to electromagnetic wave vectors on complex surfaces. Traditional display methods Unable to dynamically display the vector fluctuations of electromagnetic waves on complex surfaces
