Abstract

At least some aspects of the present disclosure feature a waveguide for propagating an electromagnetic wave. The waveguide includes a base material and a plurality of resonators disposed in a pattern, the plurality of resonators having a resonance frequency. Each of the plurality of resonators has a relative permittivity greater than a relative permittivity of the base material. At least two of the plurality of resonators are spaced according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.

First claim

What is claimed is:

1. A device, comprising:
two transceivers, and
a waveguide for propagating an electromagnetic wave and electromagnetically coupled to the two transceivers, the waveguide comprising a base material and a plurality of resonators disposed in a pattern, each of the plurality of resonators having a common resonance frequency,
wherein each of the plurality of resonators has a common relative permittivity greater than a relative permittivity of the base material,
wherein at least two of the plurality of resonators are spaced according to a lattice constant that defines a distance between a center of a first one of the plurality of resonators and a center of a neighboring second one of the plurality of resonators,
wherein the waveguide comprises a non-linear portion.

2. The device of claim 1 , further comprising:
a substrate, wherein the waveguide is disposed on or integrated with the substrate.

7. The device of claim 1 , wherein the lattice constant is less than the wavelength of the electromagnetic wave.

8. The device of claim 1 , wherein the common resonance frequency of each of the plurality of resonators is selected based on a frequency of the electromagnetic wave.

9. The device of claim 1 , wherein the common relative permittivity is at least five times of a relative permittivity of the base material.

10. The device of claim 1 , wherein the plurality of resonators are made from one of one doped or undoped Barium Titanate (BaTiO 3 ), Barium Strontium Titanate (BaSrTiO 3 ), TiO 2 (Titanium dioxide), Calcium Copper Titanate (CaCu 3 Ti 4 O 12 ), Lead Zirconium Titanate (PbZr x Ti 1-x O 3 ), Lead Titanate (PbTiO 3 ), Lead Magnesium Titanate (PbMgTiO 3 ), Lead Magnesium Niobate-Lead Titanate (Pb(Mg 1/3 Nb 2/3 )O 3 .—PbTiO 3 ), Iron Titanium Tantalate (FeTiTaO 6 ), NiO co-doped with Li and Ti (La 1.5 Sr 0.5 NiO 4 , Nd 1.5 Sr 0.5 NiO 4 ), and combinations thereof.
