Electromagnetic field analysis method for anisotropic conductive material

An electromagnetic field analysis method for an anisotropic conductive material comprising:

• setting an analytic model modeling an analytic object comprising an anisotropic conductive material to a computer, the analytic model including a first layer in which a conductivity in a predetermined first direction is different from a conductivity in another direction, and a second layer in which a conductivity in a second direction different from the first direction is different from a conductivity in another direction;
• and calculating by the computer one or more electromagnetic properties in the anisotropic conductive material with a computer software using a finite-difference time-domain method,
• wherein the calculating the one or more electromagnetic properties comprising:
• grid-partitioning the first layer by using a first computational grid having a side extending in the first direction and grid-partitioning the second layer by using a second computational grid having a side extending in the second direction;
• calculating an electromagnetic component of one of an electric field and a magnetic field in the second grid by interpolation from distribution of an electromagnetic component of the one of an electric field and a magnetic field in the first grid;
• and
• calculating an electromagnetic component of the other one of the electric field and the magnetic field in the first grid by interpolation from distribution of an electromagnetic component of the other one of the electric field and the magnetic field in the second grid,
• wherein the analytic model comprises an analytic space modeling the analytic object comprising the anisotropic conductive material and a space surrounding the anisotropic conductive material, and
• wherein the computer makes a peripheral boundary of the analytic space into a shape of a smooth surface, and only one of the first computational grid and the second computational grid is disposed at a periphery of the analytic space,
• wherein the shape of the smooth surface of the analytic space is used to manufacture the anisotropic conductive material.
