Homogeneous Medium

With this option the dielectric properties for the entire problem space can be set. This is useful for modelling in a homogeneous medium that differs from free space.

When this Green’s function is selected, the EM problem under investigation is modelled inside an infinite space of the homogeneous medium. This is the standard “free space” Green’s function similar to when the GF card is not used. The medium is normally free space, defined by material label “0”, but different parameters can be set with the DI card.
