Compared with a surface integral equation (SIE) such as a PMCHWT equation [2], a volume integral equation (VIE) is more flexible, robust, and accurate [3]; therefore, VIE is usually preferred or even the only option for complex dielectric anisotropic objects.

In cases where the SIE methods are not available, integral equations based on volume discretizations [15], i.e., volume integral equation methods (VIEs), are required.
