[28] adapted the algorithm to the isotropic dielectric model of Asami [27].
In simulation model, we also use benzocyclobutene (BCB) with the relative dielectric constant of 2.67 as the isotropic dielectric spacer, and the gold is described by the frequency dependent Drude model with plasma frequency [w.sub.p] = 1.37 x [10.sup.16] [s.sup.-1] and scattering frequency [gamma] = 2.04 x [10.sup.14] [s.sup.-1] [5, 31].
Next, a closed uniform cylindrical guide loaded with a coaxial cylindrical isotropic dielectric rod was taken up.
The structure, shown in Figure 2, is an isotropic dielectric material core, -a < y < a, surrounded by thick cladding and substrate layers of Terahertz left-handed material.
The 3D cloak was designed using inhomogeneous isotropic dielectric materials, which are realized by drilling inhomogeneous holes in layered dielectric plates.
where [h.sub.m] is thickness of the mth anisotropic dielectric layer and [h.sub.eqm] is thickness of the mth equivalent isotropic dielectric layer (m = 1, 2, ...).
Comparison of the experimental results in [11] with the results of the numerical method of this paper for the resonant [f.sub.r]equency of the fundamental mode of a circular microstrip patch on a single layer isotropic dielectric substrate of permittivity er = 2.43 and thickness d = 0.49 mm.
As mentioned above, the aims of this paper are to investigate the optical properties and switching state of 3D PCs with diamond lattices which are composed of the core isotropic dielectric spheres with surrounded by the ENG materials shells inserted in the air based on a modified plane wave expansion (PWE) method, and the unusual properties of surface-plasmon modes are also studied.
Such patterns were obtained in [13] for the dielectric-side radiation patterns, for varying heights of a source above an isotropic dielectric. The same patterns and trends are now obtained in the air-side, by immersing the dipole inside an elliptic ENZ at different heights.
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.
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.
The hypothetical configuration of the interface between two flat isotropic dielectrics with electrodes is represented by a Maxwell capacitor (Fig.
