Embodiment

[0046] 1. Theoretical basis.

[0047] The electric field strength at any point in 2D space is calculated based on the MAXWELL equations. In addition to using the MAXWELL equations, the present invention draws the electric field strength synthetic quantity in a cycle according to the characteristics of the same frequency and different phases of the X and Y components of the electric field strength. It can be found that the graph is an ellipse, and the semi-major axis of the ellipse is the composite value of the electric field strength to be calculated.

[0048] 2. Specific implementation steps.

[0049] The present invention takes a relatively simple three-electrode two-dimensional model as an example. Define the path as a straight line with a length of 10m, and define point A on the path, where point A is located in the middle of the path, electrodes 1, 2, and 3 are circles with a diameter of 0.2m, and the center of electrode 2 corresponds vertically to point A and is adjacen...

Abstract

The invention relates to a method for calculating a synthetic electric field at any point in two-dimensional space under single frequency excitation. For the calculation of the electric field strength at any point in space, the method first calculates the X and Y components of the electric field strength at the point within a cycle based on the finite element simulation software ANSYS, and then uses the The method according to the invention calculates the maximum value of the resultant amount of electric field intensity. This method has the advantages of short calculation time, high efficiency, and no theoretical error for the calculation of electric field intensity at any point in two-dimensional space.
