D(E) law: models
Introduction
This section deals with the D(E) dielectric behavior law from the perspective of the models provided in Flux.
Models
The numerous models provided are presented in the table below.
| Isotropic/anisotropic material: linear approximation | |
|---|---|
| Linear isotropic | Linear anisotropic |
| Linear isotropic with losses (tan δ ) | Linear anisotropic with losses (tan δ ) |
| Isotropic/anisotropic material: nonlinear approximation | |
|---|---|
| Isotropic spline | No anisotropic model |
Specific models are also provided (see table below). Their mode of use is presented in § Spatial model / user model.
| Dielectric property … |
|---|
| … spatial linear isotropic ( εr described via spatial formula) |
| … user ( εr described via user subroutine and personal version) |
