Dielectric mode TE01δ
Dielectric resonators - Microwave circuits

The index n of the dielectric medium is defined as the ratio of the speed of light in the dielectric medium to the speed in vacuum. It depends on both dielectric permittivity and magnetic permeability. In this article, we consider a material with homogeneous and isotropic properties. The relative magnetic permeability is equal to 1, which is generally the case for dielectric resonators. The index n is then written :

The dielectric permittivity ε_r, as well as the index n related...
