This invention belongs to the field of electromagnetic field calculation, and specifically relates to a rapid solution method for electromagnetic field distribution under varying dielectric constants. The method solves for the physical field under initial boundary conditions using full-wave simulation. In subsequent iterative calculations, whenever the dielectric constant of the material changes, a modified calculation formula is used to continuously adjust the electromagnetic field distribution to obtain the corresponding distribution. This algorithm is particularly suitable for situations where the dielectric constant of a material gradually changes under the influence of external environmental factors. This invention solves the problem of the enormous computational burden caused by repetitive full-wave simulation calculations in traditional methods for constantly changing material physical properties and physical fields. By rapidly obtaining the real-time electromagnetic field distribution around the object, the electromagnetic field radiation and electromagnetic wave leakage of the system can be observed, thus resolving systemic electromagnetic compatibility issues.
