Waveguide miniaturization using uniaxial negative permeability metamaterial
TL;DR: In this article, a rectangular waveguide filled with anisotropic uniaxial metamaterial with transversal negative effective permeability was investigated both theoretically and experimentally, and it was shown that such a waveguide supports propagation of the backward wave below the cutoff frequency, thus it can be considered as a dual of the ordinary waveguide.
Journal ArticleDOI
Non-Uniform Metasurface Luneburg Lens Antenna Design
TL;DR: In this article, an array of size-varying circular patches on a dielectric substrate inside a parallel-plate waveguide (PPW) structure with variable surface impedance is obtained, which realizes an equivalent refraction index as that of a Luneburg lens.

TL;DR: Metasurfaces are thin two-dimensional metamaterial layers that allow or inhibit the propagation of electromagnetic waves in desired directions as discussed by the authors, and have been demonstrated to be able to p...

Cost-Effective Gap Waveguide Technology Based on Glide-Symmetric Holey EBG Structures
TL;DR: In this article, a novel electromagnetic bandgap (EBG) structure, which can be used to manufacture low-cost waveguiding structures at high frequencies, is presented. And the performance of the proposed structure is demonstrated using both a straight and a double 90° bent lines through simulation and measurement.
