COMPUTER-AIDED SIMULATION METHOD FOR OBTAINING ELECTROMAGNETIC FIELD OF OBJECT

摘要

PROBLEM TO BE SOLVED: To guarantee electromagnetic environmental compatibility by obtaining the electromagnetic field of an object with the superposition of the global multipolar deployment indicating the action of electric charges and currents to a long-distance point via multipolar deployment and the local multipolar deployment indicating the action of electric charges and currents to a point via multipolar deployment. SOLUTION: The electromagnetic field of an object containing multiple partial regions and containing multiple electric charges and currents is obtained by the computer-aided simulation method. Global multipolar deployment and local multipolar deployment are implemented in the partial regions, the global multipolar deployment indicates the action of electric charges and currents to a long-distance point via multipolar deployment, and likewise the local multipolar deployment indicates the action of electric charges and currents to a point in multiple partial regions in the form of multipolar deployment. The global multipolar deployment is implemented for the investigation object sub-divided into partial regions in step 1a. The local multipolar deployment is implemented for the object sub-divided into partial regions in step 1b, and the electromagnetic field of the object is finally obtained via the superposition of the multipolar deployments in step 1c.
