Such patterns were obtained in [13] for the dielectric-side radiation patterns, for varying heights of a source above an isotropic dielectric.
A simple approach for determining the radiation pattern is using the Lorentz Reciprocity Theorem, which has usually been used for finding the radiation pattern of dipoles on isotropic dielectrics [12].
Next, a closed uniform cylindrical guide loaded with a coaxial cylindrical isotropic dielectric rod was taken up.

The GRIN metamaterial lens encompasses a non-resonant metamaterial layer that is represented by an isotropic dielectric slab accordingly perforated with drill holes of deep-subwavelength dimensions, where the desired polarization insensitivity is already fostered by the non-resonant nature of the underlying metamaterial.
As the effective permeability of isotropic dielectric and air are 1, the effective refractive index [n.
Each layer of the anisotropic substrate is replaced by an equivalent isotropic dielectric substrate with equivalent relative permittivity and equivalent height given by the following equations [29]:
The spin-on organic polymer features a low isotropic dielectric constant of 2.
To investigate the effects of anisotropy, space topology on the complete PBGs, we plot the band structures of 3D PPCs with diamond lattices containing the uniaxial material and isotropic dielectric in Fig.
Further, the resin features a low isotropic dielectric constant of 2.
The fiber core and the inner clad regions are isotropic dielectrics.
