A method for dynamic visualization of electromagnetic wave vectors on complex surfaces

Abstract

The present invention discloses a method for dynamic visualization of electromagnetic wave vectors on complex curved surfaces, comprising the following steps: S1. Reading point lists of complex curved surface models from nastran grid files [P] N Join list with points to form list of triangle surfels [Tri] M ;Initialize a data table [Tbl] with a dimension of N×18 N,18 ; S2. Calculate the unit normal vector n for each surface element in the triangle surface element list i , and computed with n i two perpendicular unit vectors b i with t i , and according to the calculation results to the data table [Tbl] N,18 Part of the data is filled; S3. process the data table obtained in step S2, and calculate the data table [Tbl] N,18 The other part of the data in the data table is filled to obtain a complete data table; S4. According to the complete data table, the complex surface electromagnetic wave vector is dynamically visualized. The invention can dynamically display the fluctuation coupling of electromagnetic waves, and effectively realizes the visualization of the vector fluctuations of electromagnetic waves on complex curved surfaces.

Description

technical field [0001] The invention relates to the field of electromagnetic waves, in particular to a method for dynamic visualization of complex surface electromagnetic wave vectors. Background technique [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.
