Current Distribution Display in Electromagnetic Analysis
The equations below are used to calculate the distribution of current density(J), the distribution of surface current density(K), and the loss (power consumption) density(P) in the 3D electromagnetic harmonic analysis.
Display setting is as in the table below. See also "Conductive Body" for details.
Current Distribution Equations
In the equations below, σ is the electric conductivity, δ is the skin depth, and γ is the propagation constant, t is the thickness of sheet body.

In the table above, C indicates that the current distribution is displayed on the conductor side. D indicates that it is displayed on the dielectric material side. X indicates that it is not displayed.
The current in the contour is illegible if all the bodies are shown. It is recommended to hide unnecessary bodies from the view.
By creating conductors with sheet or solid bodies, both vectors and contour are displayed on the conductor side, which makes the current legible.
