The case of an anisotropic dielectric medium is described by the field of crystal optics.

The simplest theoretical model is that of a homogeneous sphere surrounded by a conducting dielectric medium.

Furthermore, he was able to determine that such particles behave as a dielectric medium.

It is an electrostatic model that treats the solvent as a continuous dielectric medium.

Examples of dielectric mediums are air, paper, and certain semiconductors.

It turns out, these influences are more subtle than that of a dielectric medium mentioned above.

Below are the expressions for the various fields in a dielectric medium.

A dielectric medium is used with a specific permittivity and dimensions over which the spiral is printed.

They mostly use air as dielectric medium.

However, the specific breakdown mechanisms are significantly different for each, particularly in different kinds of dielectric medium.
