The AC Electric solver computes the electric field (E) and the current density (J) due to an AC current or voltage source. Like the Electrostatic Analysis, Maxwell’s displacement current is neglected, i.e. no propagating waves, and the size of the object is much smaller than the wavelength. Unlike the Electrostatic Analysis, the AC Electric analysis depends on time but limited to time harmonic, sinusoidal, variation. As a result, it handles perfect insulators, perfect conductors, or a mixture of both. In other words, an object can have a finite electric conductivity as well as an electric permittivity.
The AC Electric analysis is primarily used for computing conduction current density, electric field, displacement field, and potential due to an AC current or voltage. It has many practical applications, including:
After running an AC Electric analysis, you can view the following output quantities:
The AC Electric analysis can help study many devices and address numerous phenomena.
