A meta-waveguide is an advanced optical or electromagnetic waveguide that utilizes metamaterials or engineered structures to control the propagation of waves, such as light or radio waves, in innovative ways. Unlike conventional waveguides that rely on standard materials and geometries, meta-waveguides leverage the unique properties of metamaterials, which can exhibit unusual behaviors not found in natural materials, such as negative refractive index, extreme anisotropy, or bandgap effects.
