Method for analyzing electromagnetic characteristic and electronic device

An electronic device, comprising:

• a memory storing an electromagnetic characteristic evaluation program, which is used to evaluate an electromagnetic characteristic of an object unit coated with a plurality of metal dusts collocating with a power transmitting unit;
• and
• a processor coupled to the memory for executing the electromagnetic characteristic evaluation program;
• wherein the electromagnetic characteristic evaluation program comprises:
• an electromagnetic evaluation model established module comprising:
• the object unit, wherein the object unit is an arbitrary geometry shape, and the object unit has an object information;
• the power transmitting unit, wherein the power transmitting unit has an electromagnetic signal;
• and
• a simulating unit, wherein the simulating unit is defined as at least one base point emitting a plurality of beams to form a plurality of projection points, and the projection points are used to simulate the metal dusts on the object unit;
• wherein, the object unit, the power transmitting unit and the simulating unit are combined to form an electromagnetic evaluation model, a projection point coverage rate of the electromagnetic evaluation model is obtained according to the object information and a sum of areas of the projection points, and the projection point coverage rate is a metal coverage rate of the metal dusts on the object unit;
• an electromagnetic reference model established module for combining the object unit and the power transmitting unit to obtain an electromagnetic reference model;
• and
• a comparing module, wherein a radiation pattern data of the electromagnetic reference model and a radiation pattern data of the electromagnetic evaluation model are obtained by the electromagnetic signal, respectively, and the two radiation pattern data are compared to obtain an electromagnetic gain difference value, so that a composition of the metal dusts or a position of the power transmitting unit based on the electromagnetic gain difference value to meet a requirement of an installation is adjusted.
